Hey, so I was listening to a band called Simple Plan and this just kind of happened. Here you go. :)
It was late and Amy knew she should have been in bed, but she just couldn't sleep. It didn't help that the Doctor gave her and her husband an uncomfortable bunk bed to sleep on. Frustrated, she got up and decided that she was going to find the Doctor and finally make him give them a better bed. She was tired of waiting for him to quit ignoring her and Rory's pleas. She knew that the Doctor would be up. After all, he didn't need as much sleep as humans.
Amy walked down the TARDIS hallway to the control room. She figured that it was a good place to start since the Doctor liked to tinker with his precious ship. However, when she got closer, she heard talking. Curiosity getting the better of her, she moved closer until she could hear clearly.
"Hey, Rose. I-uh-I don't usually do this, but I miss you. So much. I-" Amy heard the Doctor sigh. "Remember when I said 'I'm always okay?' Well, I lied. I'm not okay, and I'm tired of pretending that I am."
Towards the end the Doctor's voice cracked and he took a deep, shaky breath. Amy knew then that he was talking to someone who was probably long gone. He was alone. She knew that she was invading his privacy and that he would be angry if he found out she was there. However, she couldn't help but stay where she was when he started speaking again.
"I'm sick of the pain and I'm sick of hiding it. You were the most amazing thing to ever happen to me and now you're gone. You promised me you would stay forever. I was stupid and let myself believe that for a while. I knew in the back of my mind that it wouldn't last. Even if you stayed until your forever was up, I would have still lost you eventually.
"Still, it would have been longer. I would do anything just to see you again. I went back to see you before I regenerated, did you ever realize that? You were the first and last face that my last body ever saw.
"That was supposed to be my final goodbye to you. I thought that I could see you one last time and forget about the loss. I thought this regeneration would be different; I believed that the pain would lessen, but it didn't. I am better at hiding it now, but that's about it. I wear a mask around everyone. I act so carefree this time around, but I will always carry the burden of losing you.
"You know, I could wait forever if there was even the slightest chance of you coming back. I hope you know that. I know I gave you to a human me, so you probably wouldn't come back even if it was possible. With him you can be happy. He has one life so you can both have forever with each other. The one adventure I can never have.
"Rose Tyler I- I don't even know why I'm talking to you, it's not like you can even hear me. I guess I just need you right now. It's been so long, and I still feel the same. I'd do anything just to have you here."
The Doctor paused for a moment trying to gather himself, debating whether or not to say what he has been holding back for so many years. "I love you," he cried as he finally broke down, his body wracking with the force of his tears that he never before let himself shed. "I'm sorry, I'm so sorry," he managed to push out past the sobs.
Amy's heart broke for her Raggedy Man. The only side she ever saw of him seemed so happy, so energetic, so child-like. She realized that she really should give him some privacy now. As she turned away to go back to her room, tears were streaming down her own face. She wanted to console him, but what could she say? What could she do? He would probably just make her leave him alone anyway, especially since she just invaded his private moment. One thing she knew for sure though was that if the Doctor could wait forever for something that would never come, then she could wait another night for a new bed.
