The only way to cure OCD is to recondition your brain. You know how society conditions you to believe in something, to behave in a certain way, that's what OCD does, too.
It conditions you slowly, over a long time, to behave in a repetitive and physically/mentally-draining way. And it will only get worse as this mental disorder takes over your mind and alters it.
To recondition your brain you must practise the Buddhist technique of meditation, to clear and empty your mind, and focus on your connection with nature and existence rather than your connection with the things around you.
Meditate like this, detach your mind from your brain, learn to numb your senses mentally, and focus only on yourself, and nothing else.
Do this for 15 minutes a day, everyday, and in 3 months or more, depending on how much effort you put into it, you will have reconditioned your brain to overcome OCD.
