Recently I've been doing better, I've been on Zoloft for over a month now and it's helping a bit but today I just woke up feeling awful. The whole of last night I kept dreaming that I had lost my mind and couldn't remember anything and that everyone hated me, today I just feel so low and anxious. I've got three exams coming up that I haven't studied for because I've been too depressed/anxious, how can I get out of this bad mindset? This depressive episode has hit me like a train for no apparent reason overnight, it's like I can't move or function. Any and all advice is welcome, I just want to shake this feeling of impending doom.
