ocd

hi all

ive just joined up my son appears to have ocd , he soakes his clothes one by one in a full tub of water , the water appears to be crystal clear then he empties it to soak another article , i,m worried about him

now he wont even travel in my car since its too dirty . he has had breakdowns back in his school days and didnt complete his uni course despite him being of high intelligence we bought him to see a child psychiatrist when he was going to school but he refused to take the mild anti depresents that were perscribed for him he had a very patient and caring gp but now dosent want to see her again he is sure that there is nothing wrong with him , i was just wondering if someone can advise me of haw i can get him some help , thanks
