What kind of therapist? First, you didn't have OCD because there was no C, you just had O. Second, you quit Paxil without consulting a psychiatrist? It can be murder or it can be easy or in between, everyone's different, but it should never be done without careful weaning with a psychiatrist who understands Paxil withdrawal, and most don't. As to how long you'll suffer, nobody can tell you that because we all have different experiences and metabolisms.
