help?

I don't know what's wrong with me any more... I have no motivation for Anything. Literally anything. Small tasks are hard to get up and do. My body aches and there are days I can't even get up because I can't find the motivation to get out of bed. I miss up everything I try to do. Band and cross country tryouts are soon and I haven't practiced at all. I'm not gonna make it and that's gonna make me feel worse. I have a terrible body image. My sex drive is gone and I always feel terrible and I've broken down in tears over the smallest things... Idk anymore...
