I hope it is ok to post here even though I have schizoaffective....

Well, everyday, I ask why I bother....only to get no answer. It seems like everything I do is never good enough. I do one thing, only to get told that I was supposed to do something else. Today, my mom told me to get the spray for the grill. I had no clue which spray. She yelled at me and I ended up crying. I can't deal with it anymore. I'll probably flunk college too when I go back, if I don't end up back in the hospital. I'll never amount to anything. I am just another rock under the waters of despair. I feel like this everyday. I have no energy anymore. What is the purpose to anything?
