As someone who suffered from severe OCD, I feel for you. I know that you probably understand what you need to do (intellectually) to reduce your compulsions but you can't seem to do it. It's not for lack of wanting to be rid of the time consuming rituals either. I get it.

My best advice is to find yourself a professional who specializes in the treatment of OCD. The international OCD foundation has a database of certified practioners on their website. I would start there. The problem with OCD is that many therapists say that they treat the condition but in truth do not have the extensive training required to truly understand the disorder. There is no shame about getting professional help. In fact, it's a disorder that can very easily get out of control and from personal experience, is very hard to treat on your own. Having the understanding, support, and knowledge of someone who knows the condition inside and out is invaluable in the recovery process.

You probably know this but the most effective treatment for OCD is a combination of medication and cognitive behavioral therapy (specifically a therapy called exposure response prevention -ERP). It basically consists of gradually exposing yourself to the trigger (i.e. first think about something "contaminated", then touching something "contaminated" and waiting five minutes before using hand sanitizer, then touching something "contaminated" and waiting ten minutes before using hand sanitizer, etc.) until the trigger no longer causes the compulsion. It's difficult and feels horrible and you feel worse before it gets better.

I went to Rogers Memorial Hospital in WI for the treatment of my severe OCD. They have both a residential and an outpatient OCD program and it worked wonders. When I went in, I was obsessing and doing rituals every waking minute. When I left, I was 95% OCD free. I know that hospitalization sounds a bit extreme but for some, it's the intensive support and reliable structure that they need to really beat this disorder. Just wanted to throw that out there.
