You need to engage in exposure and response prevention, it's literally the only way. Even if you can't afford a therapist try doing it on your own. I've had OCD for well over a decade now and while I still struggle a lot, things have gotten significantly better for me. You could also try reading through this guy's website if you have Pure O, it's helped me a lot as well.
