I don't know what to do anymore. I was starting to get better and then I developed a crush on someone and I think she likes me back and now I can't function. I'm in so much pain, it's torture. I'm scared she hates me, I think I hate her, I want to ignore her, I want to constantly talk to her. I feel like absolute shit, I'm completely overwhelmed and I'm engaging in self-destructive behaviors again. I would appreciate any advice.
