I've been in that dark place. I was taken by OCD all day, so much that I quit school, for majorly depressed, was almost non living aside from the OCD.

What meds are u on? What kind of therapy did u do? Behavior therapy is amazingly helpful. I suggest buying the book "talking back to OCD". It is aimed for a younger person, but the ideas are the same. You can work through it without a t, but I suggest u work with one. I would talk to your doc about changing meds, as it seems like the one you are taking isn't helping enough. Also, I think that you should give therapy another try.
