I cant add much to the answer Lara gave, other than to mention Cognitive Behavioral Therapy which seems to really help many people cope with the OCD symptoms that are most troublesome to them

It is really important tho to find a psychologist who is not only well trained in CBT, but who also has a gentle and compassionate manner. The first one my son had was a bit domineering and "take charge and change you" in manner and that was not what we wanted at all. Once we found the right therapist, the benefits were really notable! and my son learned so much about coping mechanisms and his OCD

Here is a bit more info on CBT
