Thanks and Enjoy ;)

Celestia had to raise and lower the sun and moon again like she did for 1000 years because Princess Luna was in the Canterlot Castle hospital wing after her episode of insanity, it had been a month ever since Luna had been admitted to the mental institution and that she might be out before Celestia's birthday, Celestia almost always during her free time visited Luna to see she was doing, Celestia would normally converse with Luna and often ask her why she hurt herself so badly during her last incident. "Luna I don't understand why you would hurt yourself so badly," Celestia asked with lots of concern for her younger sister, Luna's stitches had been removed and her scars were still barely visible, it had only been two days since the stitches were removed anyway, Luna turned to her sister, "Do not fear for me sister I'm perfectly fine, I just needed some time from the stresses of taking care of the nights," she smiled calmly, Celestia had a look of concern on her face seeing her sister so relaxed and not breaking down. The nurse stepped in and told the sisters that visiting hours were over, the two hugged each other goodbye and Celestia walked out of the institutional facility when she bumped into Dr. Hooves, "Oh forgive me your highness," he bowed his head in respect, Celestia bowed back and greeted him, "Good morning doctor, are you heading in to see Luna?" she asked, Dr. Hooves nodded and replied, "Yes your highness, I'm the pony that has been rehabilitating her and I will deem her ready to leave when I see that rehabilitation is helping her," Celestia sighed in relief, "Thank you doctor it means a lot to me, I just hope she'll be released before my birthday," Dr. Hooves nodded in agreement and left to see Luna. Celestia returned to her study to see her star pupil, Twilight Sparkle reading a large book, Celestia walked in and asked her, "Are you enjoying that book Twilight?" Twilight's head shot up when she heard her mentor speaking to her, for she had not noticed her entering, "Yes indeed Princess it is very exciting," Celestia layed next to her and asked her to read for her.

A few days later...

Celestia was excited today which she rarely was for any other day, today however was different it was the day that Luna would be released from the institution, Celestia had to sign her out being her only relative and guardian. Celestia gained the news when a letter from Dr. Hooves was sent to her and when she read it she could barely contain her excitement, Dr. Hooves had diagnosed Luna with stress induced hallucinations, when somepony sees a darker representation of themselves and the pony feels that the only way to stop this is to hurt themselves and have episodic breakdowns, the most common cause for this is mainly stress or mixed emotions about certain issues. Luna was scheduled to leave the hospital at about 10:30 am, when it was ten minutes before the time Celestia walked towards the hospital wing to sign all the paperwork and pay for the rehabilitation that Dr. Hooves had given Luna, after everything was done Luna gathered her belongings and left with her sister looking more relaxed than Celestia had thought, "Sister I'm so happy to see that you are all right," Celestia hugged her younger sister, "Do not worry yourself Tia I am well enough to know that I must have my anxiety pills after I have eaten, Dr. Hooves said it is easier for them to digest if I have them after eating," Luna smiled as she and Celestia walked.

Luna entered her room and saw the state it was in, she sighed, realising what damage she caused she used her magic to repair everything including her broken mirror, after everything was repaired she looked at her clock and saw it was midday, she smiled and went to the dining room to see her sister, Twilight Sparkle and the other elements of harmony sitting waiting for her, she smiled as she took her seat across from Twilight, next to Rainbow Dash and next to Celestia who sat at the head of the table, the lunch was a good one at that, during the main course Pinkie was speaking to Princess Luna who she had not seen fro over a month, "Hey Luna where were you for the past month? Were you sick? I remember when I'm sick I can't move or do any of the tings I love to do because obviously I'm sick," Luna's eyes went wide seeing the pink earth pony rambling away, and in the back her mind she heard, "Ugh what a disrespectful earth pony she should know that I am a Princess I should not be spoken to like that, always blabbing her mouth off about something stupid, and it's always party this and party that it just drives me crazy, I swear she should be the one to be locked up in the mental institution," Pinkie Pie had stopped speaking and Luna looked around the table snapping out of her trance, seeing eyes turned to her including her sister's. Suddenly without warning Pinkie ran out the room crying, Applejack excused herself and ran after her, Celestia only stared at her sister, finally Luna worked up the courage to ask, "What?" Rarity adressed her, "Uhm... your majesty... you seemed to say some rather harsh things about Pinkie Pie and I don't believe you realised what she said," scratching the back of her neck uneasy, Luna suddenly realised that what she heard in the back of her head actually came out in words, "It's probably still the stress I haven't taken my medication," after the two earth ponies reentered the room Luna walked over to Pinkie and gave her hug, "I'm sorry about that Pinkie I don't know what happened, but, hopefully you can forgive me, for I wish to explain to everypony here on why I was gone," Pinkie smiled again and accepted the apology.

During dessert Luna told the others on why she was gone, "So there you have it I have been diagnosed with stress induced hallucinations and normally the side effects include saying things you are unaware of until you hurt somepony's feelings and is caused due to stress or mixed emotions on certain topics, but, if I take my anxiety pills then it's no problem, but, the doctor says that if I take them after a meal then it will be easier for it to take effect and will be faster too," Twilight's friends looked on in disbelief, finally Applejack said something, "So what ya sayin' is that if ya get too stressed out or ya have issues with certain topics ya go nuttier than a squirrel on coffee and normally hurt ya self ta get rid o' the darker reflection o' ya self or say things that hurt other pony's feelin's," Luna bowed her head and only replied, "Yes and if I don't take my anxiety medication it could get a lot worse," the other ponies around the table all looked at each other, then the chefs brought in dessert, cherry pie, while they were eating their cherry pies, Luna looked to her left and saw Rainbow Dash looking at her, luna had a questioned expression on her face, Rainbow finally asked, "Soooo... how strong are your wings," Luna was taken aback by the question, and then answered, "Pretty strong actually. They can take me great distances without tiring, does that answer your question," Rainbow Dash smiled at her idea, "Maybe we should have a race so you can prove it someday," Luna chuckled friendly at the suggestion, "Maybe we could Rainbow Dash." The remainder of dessert went on without any further incidents, Twilight said goodbye to her friends and returned to her room in Canterlot Castle seeing as how she would be staying there to help Celestia watch over the castle or Luna incase anything happened again, as she was returning to her room she passed the throne room.

She saw Princess Luna standing infront of the throne, it was almost time for Luna to raise the moon for the first time ever since she was admitted to the hospital a month ago, Luna was just standing there and Twilight had to do something feeling concerned for her, she approached Luna cautiously, "Princess Luna... are you okay?" Luna turned her head to see Twilight Sparkle standing behind her, "Yes Twilight I'm perfectly fine, Does thou want to see the moon rise?" Twilight looked at her and smiled, "I'd love to see how you make the most beautiful nights, I've never seen you do it before," Luna smiled at her seeing that somepony wanted to see her beautiful nights being made firsthoof. They went to Luna's balcony and when the sun had been lowered she rose the beautiful moon, Twilight looked on in awe to see how beautiful Luna made the nights and that nopony except herself and Luna appreciated it, "I love how you make the night Luna it's so beautiful and I don't see how other ponies don't appreciate it," Luna smiled at her, "Thank you Twilight I appreciate what you say, for that's how I felt before Nightmare Moon surfaced for the first time, but, now I see the significance in it, if I didn't make the nights so beautiful astronomer ponies wouldn't be able to see the constellations," Twilight looked towards the moon, she had to ask Luna this, "What was it like on the moon?" Luna began to cry, Twilight regretted what she had just asked she wanted to leave, "It was very lonely, I only had Nightmare Moon with me and... and..." she began to breath more quickly now, her voice then changed and used her magic to lock her bedroom door and the door leading to the balcony, "I was all alone and my sister was the one that put me there for 1000 years and when I returned to my normal state most ponies fled at the sight of me and I make beautiful nights and so few appreciate them," she was using the Royal Voice and Twilight saw that Luna was beginning her metamorphosis. Luna was growing taller, tears were streaming from her glowing white eyes, her wings began to change, Twilight had no other option, she had to get Celestia.

Celestia was in her study when her window swung open behind her head , "What is going on?" she looked out and saw Luna ascending into the sky, a movement she knew all too well and she also saw Twilight trying to reason with her, she flew out the window and went into Luna's bedroom where she found the anxiety medication and she used her magic to turn it into liquid form and a syringe from the first aid kit, meanwhile outside Luna was still ascending and the night began to grow darker as if a shadow was covering the land, Twilight called to her, "Luna you have to stop this, if you don't Celestia will banish you again," Luna looked down at her friend tears still streaming form her glowing white eyes, "YOU FOAL YOU CANNOT STOP NIGHTMARE MOON!" she cackled like her dark side and then she felt a sting in her fore hoof and she slowly descended back to the balcony, panting and seeing the concerned face on Twilight's face and Celestia's, Luna collapsed into sleep, Celestia caught her with her magic and helped her to bed, the night had returned to its natural beauty like as if the shadow was withdrawn, Celestia placed Luna into her bed and unlocked the door and she left with Twilight alongside her, Celestia sighed, "Why now my sister why are you having these incidents?" Twilight just sat there trying to process what had just happened, "Princess Celestia what are we going to do about Luna," Celestia turned to her student, "I shall send Dr. Hooves a letter and see if he come as soon as possible and see if he can help Luna," Twilight used her magic to help Celestia write the letter and sent it on its way, and a few hours later, Dr. Hooves was standing at the Castle door, Celestia and Twilight greeted him as he entered, "I came as quickly as I possibly could your majesty,"

"Thank you doctor I don't know what's happening, Luna just had another incident and this time she almost became Nightmare Moon again,"

Dr. Hooves looked at her curiously, " That's strange, has she taken her medicine?" "Yes she does, but, she must have forgotten to do so before raising the moon," Twilight said as they walked to Luna's bedroom, "I had to use my magic to turn it into a liquid form and inject her with a syringe from the first aid kit and she calmed down instantly," Celestia continued, Dr. Hooves was still confused, "If it took a quick effect on her in a liquid form then that means she already took her medication, I just can't explain it," as they reached Luna's room they entered quietly as not to wake her, but, they found her sitting upright staring at her mirror, she seemed to be having an argument with some pony, the three only opened the door to see what she was saying, "Damn you Nightmare Moon, I can't believe you did that to me," the three took notice that she was talking to herself, she continued, "You're not a good mare Luna, just let yourself go and show Equestria and your sister on what we can do," "No! I shall not be banished again I hated being alone on the moon and I don't plan on goin back there soon..." Dr. Hooves closed the door and sighed and turned to the two alicorns, "It's worse than I thought when I was rehabilitating her, she normally got aggressive and then regretted the behaviour minutes after the incident," Celestia and Twilight looked at him with concern, he continued, "I'm afraid Princess Luna has IED or Intermittent Explosive Disorder she has aggressive attacks and can't resist them, then after the attack has taken place the pony will feel regretful or embarrassed about the behaviour and I have ruled out any other disorder, they will destroy property or have angry verbal outbursts and will cause harm to themselves, I will have to ask you to send her to Psychotherapy and I will give her mood stabilisers and more anxiety medication," Celestia looked down towards the floor holding back tears, Twilight had to ask Dr. Hooves, "How can we prevent these attacks form happening again?" Dr. Hooves turned to her, "She needs to practice relaxation techniques, this includes deep breathing or yoga, she must avoid or leave situations that will upset her and importantly she must stick with her treatment, she has been prescribed her medication you must make sure that she takes the medication, I cannot express the importance, even if you have to force her to take it," Twilight thanked the doctor and he left for Ponyville.

Twilight had explained to Luna that she had IED and that Luna must avoid or leave situations that will upset her, practice relaxation techniques such as yoga and most importantly stick with her treatment, Luna accepted what she had to do, she often saw the Psychologist pony when she visited Luna for their sessions together, she always took her medication as prescribed and often did yoga or aroma therapy to calm herself and for the following weeks she managed to keep her episodes on the down low only losing it at certain times that stressed her when a pony wondered how it was like to be in a mental institution or be on the moon. Luna looked at her calendar and saw that Celestia's birthday was in just five days, Luna went to the ballroom to see how it looked for her sister's birthday and she was surprised on how much Pinkie Pie could do in a few months that looks like a party a year in the making, she saw the pink pony and saw the amount of balloons that were to be filled and the amount of helium tanks to make all those balloons float, Pinkie noticed the Princess and called to her, "Hey Princess Luna come over here I made you something," Luna was shocked to hear that somepony had made her something, she approached Pinkie and saw that she was holding a beautiful small cake in the shape of her cutie mark, she began to cry with tears of joy and hugged the pink pony, "Thank you Pinkie I love it," Pinkie hugged the Princess back to show that she truly accepted Luna's apology for the incident a few weeks ago, as Luna turned to leave with her new cake she called back, "Keep up the good work."

As Luna entered her room she set her cake down on the desk by her bookshelf for she wanted to savour the moment before she would eat it, she then went to her cupboard and took out her dark cloak for she needed to buy Celestia a gift for her birthday, as she turned to her balcony after she saw the sun beginning to lower she then glanced into her mirror and only saw her reflection staring back at her and said to herself, "I am a good mare not a mad one," and she left to Canterlot to find a gift for her sister, she entered a jewellery shop and browsed to find something her sister would like, then she found it a golden necklace with a sun shaped yellow jewel in the middle, she picked it up with her magic and took it to the shop owner, "Well I see you have taste in jewellery, so who's the lucky somepony that's going to receive it?" Luna's hood was over her head so the shop keeper wouldn't recognise her, "It's for my sister," "Is it her birthday?" the shop keeper questioned, Luna removed her hood to reveal herself and said, "Yes it's a gift for my sister Princess Celestia," the shop pony only smiled, "I was wondering when you'd get your sister's gift," Luna only chuckled, "Better late than never I suppose," "True," the shop keeper put it into a beautiful box and wrapped it in a beautiful wrapping paper as well, "That will be 100 bits," Luna paid her and left with the necklace thanking the shopkeeper for wrapping it and everything. She flew back to Canterlot castle, just in time to raise the moon, after she had raised the moon, she divulged into her delicious cake, "Mmmm, red velvet my favourite," she thought to her self as she ate the cake, after she was done she wrote a letter adressed to Pinkie Pie to thank her for the cake, she then had her prescription medication and looked out into Equestria and all it's beauty at night, she saw a few ponies frolicking in the moonlight, so she made it brighter so they could see better at night, she smiled to see the few ponies appreciate her nights. She then felt something stir inside her a certain feeling she had not felt within a few weeks she turned to her mirror and saw her standing there, "Go away already, I don't need you anymore," "Do you really think that it's so easy to cast away yourself and who you truly are?" The reflection said, "You are not real you are just a hallucination of what I have shed long ago, I have IED anyway," Luna replied to the reflection turning her back on her, Nightmare Moon began to grow impatient seeing that she was not winning the battle, suddenly the reflection jumped out of the mirror and phased into Luna, Luna gasped in pain she looked into the mirror and saw her face was in half, on the right was Princess Luna the young and beautiful mare of the night and on the left was Nightmare Moon her helmet on her head and her mane flowing and more darker than her own short light mane Luna began to cry tears streaming from her eye and Nightmare Moon began to laugh her fangs bared while laughing that turned into her cackle. Luna turned away quickly and looked back into it, she saw herself normally again no Nightmare Moon, she sighed in relief, "It was just a hallucination," she turned to her bed and tucked in as she lowered the moon to make way for the dawn. She said to herself as she was falling asleep, "Just a hallucination, just a hallucination... just a hallucination," she began to sleep soundly as her eyes closed and she slept.
