Smiley21,
I think that you should go to a doctor, get a check up, and see if you are suffering from a physical illness. If that is ruled out, ask for a referal to a psychologist or psychiatrist depending on what the doctor thinks. Depression and OCD are nothing to fool around with. There are medical treatments such as medicine and therapy out there that can help you. I strongly recommend that you utilize them. You will be glad that you did. I wish you the best.
