Obsessive Compulsive Disorder (OCD) Support Group
Obsessive-compulsive disorder (OCD) is a psychiatric disorder, more specifically, an anxiety disorder. OCD is manifested in a variety of forms, but is most commonly characterized by a subject's obsessive (repetitive, distressing, intrusive) thoughts and related compulsions (tasks or rituals) which attempt to neutralize the obsessions.
Maybe talk to a counselor or figure out ways of recognizing when you are doing it and maybe explore the feelings leading to that. You know, same old "keep a journal and find the answer" thing.
Best of luck!
