I Can't Concentrate At All

So, I m supposed to be functioning and all, right. I m supposed to be a good student... And here I am completely unable to concentrate. I can t concentrate in class. I can t think. I can t do anything. I am depressed, can t get myself to do anything. I feel like I m going to fail in school completely. I can t study. I am incapable of everything. I feel like a failure. I don t know what to do. I don t like being incapable of thinking, studying, so on... I really don t. I need to study.... I Can t Concentrate At All
