there are lots of herbal/vitamin remedies on market ( i just googled
for natural remedies
for OCD) that included remedies called amoryn, mindsoothe, purecalm and so on, i didn't use any of them, but reading the testimonials, there were many from previous ocd sufferers who got help from the herbal products, maybe they could help you too. Also, a woman called Mary Reed cured her own ocd with natural remedies and now helps others with the stuff that she used on herself to get better.
