So if you can somehow stop the compulsion part(telling brain there is no logic in what you are going to do , it is ocd) can u overcome ocd gradually?

Cues, counters: The keys to countering obsessions & compulsions are: developing an awareness of what your cues or triggers are, engaging countering behaviors (e.g., progressive relaxation, challenging automatic thoughts, distraction), & tracking the success of your counters. Medications can be a big support as well. A licensed cognitive-behavioral therapist can help you develop strong skills!
