my advice, let the anxiety come, let it hit you hard. but dont give into the compulsion, the more the anxiety hits, each time is less and less. its about just BATTLING.
Stay away from medication.
I am 35 and have ocd for about 15 years. To begin with it focused on checking things, and then moved on to cleanliness. I went through some very very dark times, and received CBT and various meds. To cut a long story short I am now on low dose a/d, one which controls my ocd, I am a mother of 3 and I work as a healthcare assistant (which involves body fluids). If someone had asked me 12yrs ago if I could have worked in this job I would have laughed - I never thought I would be able to get on with my life.
I just wanted to say get help if you can because if you leave it it will just escalate, identifying you have a problem is the first step. It is more common that you think and certainly nothing to be ashamed of. There is light at the end of the tunnel, I am living proof. I get on with my life, yes I have the odd "moment" but mostly it doesn't stop me doing anything
Take care
