Why

Why am I here?

I woke up, covered in a sweaty mask. Gross. I couldn't feel my left arm, and my shoulder hurts like crazy. I looked around, and I realized I was in a mental hospital. I wonder what I did now. I always did things I shouldn't, but, this is my first time in the mental hospital. My vision was blurry, but I could still see the figure in the window at the door, which was someone I've never seen before. She seemed calm, and sweet when she walked in, which I knew was a act. I got up, and glared at her. "Where am I?" I looked down, and I wasn't wearing my shirt I put on. "You're in a mental hospital, sweetie." She smiled as she said. "That's obvious, but, I am not home. Why am I here in the first place?" I tried to stay calm while I spoke. "Your parents said you've been acting strangely, and when we tried to talk to you, you kicked someone in the stomach." She said it like she has said it a thousand times.

 I don't belong here. I didn't do anything. "You are just going to be in here for a bit, so we can make sure your not.. y'know.. insane." She didn't say anything after that. "I know for a fact I am normal, and I am far from insane." I grinned. "Just let me go, okay?" She seemed rather annoyed when I said that, then she walked out without any other word, and she left behind a letter. I picked it up and it read, Dear, Addison, I hope you're okay. This is not a mental hospital, and this isn't even close to one. You need to get out. They didn't read this yet, but whatever you do, don't ask 'Why'. What is that post to mean?
