I've had OCD my entire adult life. Things improved greatly for me when about five years ago, I took my OCD to my Doctor.
I am fortunate that an SSRI (paxil) greatly helps to shut my unwanted / obsessive thoughts down. Been on it nearly three years.
Healthy diet and vigorous exercise helps. I also just started cognitive behavioral therapy with a psychologist.
So my advice is get yourself to a Doctor and be honest.
I'm nearly 6 months sober.
