Hi i suffer from ocd also and have been a certified candidate for nearly two decades now, and i know the intensity that each individual goes through although our physical traumas differ. One of my experiences was that I was plucking my facial hair in one particular section of my beard which ended up leaving a gapping hole of similar look like ringworm. The reason for this is i was looking for some stimulation and distraction to counteract my intrusive thoughts that go along hand in hand with ocd. I told one of my treating therappists at the time in which we were doing CBT without any medication at that time, And as crazy as this may sound coming from a therapist he suggested that I wear a loosely fit rubber band around my wrist and that any time the urge and compulsion came along that I should pinch myself with the loosely fit band. I have to honestly say it was hard and I persued with it for some time.Somehow now I still have the same gapping hole in my beard but it has remained the same size.Please dont despair and unless you have done so already i would suggest Cognative Behavioural Therapy also. Take care!
