What is wrong with me?

Well, how can I describe this? I've been feeling weird lately. My mind feels like it's out of control, I can't think straight, I feel like there's no hope, and I feel like I'm not in my own body. Ever since this happened my memory has felt rusty. I feel like I'm not myself, it's like i'm not in my own body. It's like I'm there but I'm not. I do have stress and anxiety, by the way.
