I find whisper's idea of running up and down the stairs to be a healthy coping mechanism.

But I also agree that judging yourself for thoughts you can't control will only make things worse. Try and remember that your thoughts are not your actions. You can't control your thoughts, but you can still go to church and be a good Christian.

My brother has severe OCD too actually. He also can't read or do anything. I feel powerless, because there doesn't seem to be anything I can do to help him. Would it be possible for you to see a therapist? I don't know what the mental health system is like in Nigeria.
