A/N - Not inspired by any particular prompt

No stranger to sadness, Anna was tired of many things. Tired of the way life had turned into. She was reaching her final straw, soon her tolerance would snap and the world around her would come crashing down with it. Complaisant, Anna rolled with the punches life had to offer, the majority of them thrown onto her by Elsa. It was a difficult relationship. The younger sister spent years actively working to create the home that should have been. She had put up with Elsa shutting her out. She had even accepted Elsa's recklessness. Giving up everything, and losing to death once more, Anna was certain that when she saw her sister on the horizon, looking like a brand new person, that the universe was repaying what they had owed her. She was sure that this was the beginning of a brand new, happy, life.

But it never turned out that way. She was left, again. Elsa was once more the source of her pain. Distance, there was so much of it. Elsa rarely ever visited. She built a bike for Olaf, and spent months trying to grow flowers with him, they were together. Kristoff, of all people was living in a castle, a place that brought him discomfort, but he was here. And that's what hurt the most. Elsa had the availability, all she did was frolic around the forest, at least that's what her letters hinted.

Letters, those damn letters. Everything was always so open to misinterpretation. For Anna especially, she found herself having to categorise every last minute of her day by importance. Where she would otherwise ramble with Elsa about breakfast she had, or other meaningless conversation, Anna quickly realised that could take up a page. Elsa put deep thought into everything she did, everything movement had purpose. Her letters were so much shorter. And so, Anna felt she had to match that, she had no clue what the appropriate letter length was, and if Elsa was so busy in the forest - which she had to have been given she couldn't instead visit the forest and stay home, in Arendelle - then she should shorten her letters too. She hated it, truly. Inside jokes with Kristoff and Olaf didn't translate well on paper and she so desperately wanted Elsa to feel included.

But then, why should that have mattered? Elsa ran off to be the fifth spirit and the drop of a hat. It had hardly taken any convincing, Honeymaren had said you belong here and Elsa was gone from her side. That was what hurt. That she had spent years assuring Elsa of the same exact thing, and it amounted nothing. When Elsa worried she wasn't good enough, that she was failing Arendelle, she spent hours in her room reminding Elsa of her importance and how much she was needed in Arendelle, how much Anna needed her as a sister.

After killing herself, it seemed like nothing. She was gasping for breath at that beach, her mind trying to piece together just how everything worked together. There her sister stood before her. Aside from wearing a smile on her face, and light tears in her eyes, the picture before her was a Queen holding her own. Like always, Anna was feeling more than those around her. It was bizarre, at times she couldn't help but wondered if she was overreacting. But she wasn't. Not at all. She should have got used to it by now, putting more into the relationship than she ever got back. It had been that way all through childhood.

Slowly, Anna was realising this remained unchanged. And it left a bitter aftertaste.

With her limited time, she spent most of it trying to timetable a visit to Elsa, and all too quickly she realised her visits only exacerbated her feelings.

It's the sinking feeling when there wasn't a door to knock on.

It's that pain in your heart as you realise that two worlds are slowly turning, the axis of rotation no longer in sync and all askew.

It's the way her hair looks different, and you can't pinpoint why.

It's the hard hitting realisation that she isn't there to celebrate your successes. Instead, they merely become the morning newspaper, something to thumb through in weekly letters that earn a small smile. It's not enough to feel the way you did when it happened, because she is learning about it too late. She wasn't there. The jokes have been and gone, the laughter merely an echo that Elsa can barely hear.

That's what living with grief truly boils down to, longing to be near them. Wishing that they were standing beside you, to hear her voice in the next room.

And it was clear Elsa did not feel the same. She toured Anna around the forest, showing her all the hiding places and views. Introduced to everyone in camp, Anna listened as Elsa listed things about them. In the short time she had been there, Elsa could have wrote a book with all she knew about Honeymaren.

She bit her tongue through it all. Sitting quietly stewing on how much she had to work to even get Elsa to talk to her. Yet here she was, effortlessly and seamlessly creating a family of her own in the middle of nowhere.

"You should talk to her, Anna." Kristoff spoke sincerely.

"I wouldn't know what to say" Anna blinked. "If I wrote it down it would be too long, she wouldn't read it." Anna sighed.

She sank deeper into the sofa, willing the painful feeling in her chest to go away. The end was coming, Elsa was leaving. Anna was nothing more than a pit stop to a better life. She had taught her everything she knew, and now it was over.

She didn't think to ask Anna. She didn't stop to think about how it would destroy her.

"She would, of course she would Anna, she's your sister." Kristoff moved across the room and kneeled beside Anna.

"You don't understand Kristoff. I need her, but she doesn't need me." Anna breathed, swallowing the lump in her throat. "If she had given me time it would have been okay, but she didn't even say goodbye..." She had been left to figure it out for herself. Once again, an Anna trademark.

You're not coming home, are you?

Ahtohallan changed me, I don't know how the forest and the spirits need me now, but I wanna be there when they do.

She was the one to make the first move. Days like this, she wished she hadn't asked. How would Elsa have told her? Or would Elsa had to have gone missing for the truth to be out?

"You'll always need each other." Kristoff commented.

"Tell that to her, not me." Anna groaned, pressing a cushion into her face.

A/N - An abrupt ending I know, I wasn't sure how to continue. Plus I've done a story similar to this, was worried it would end up down the same route. I'm still taking prompts! This was just a one off thought, I tried to execute something and it didn't quite work out.
