There is and there isn't. The trickiest thing with these mental issues is that it goes from person to person what will be needed to truly cure it and if thats even possible.
I have OCD and while I lack knowledge of what pure O is I know how it feels to have it be constantly harassing your mind 24/7 leaving you feeling like there is no escape from it while still alive.
There are ways of therapy that have cured some peoples OCD, for example exposure therapy has cured some people straight up leaving them without any signs of their OCD. Cognitive behavioral therapy is another way that has helped many others suffering with OCD.
For me both methods left my OCD unchanged, no medication has worked yet either.
I can't really put how bad I think OCD is into words because there really aren't any words specific enough to describe the torture the mind forces you to go through so I hope that the therapy or medication available to you (if any) will help you out and maybe even cure your OCD.
All that said if you're looking for mostly short term ways of potentially relieving yourself of the OCD here are some things I do but bare in mind this is not me recommending them exactly simply saying this is what works for me if I desperately need short/long term relief and sometimes even if the methods are bad its still better mentally than to let the OCD run wild sometimes.
Short term: Self-harm, Alcohol, Snus (tobacco), Weed, Eating/Drinking something I really enjoy, Sexual relief, Music, Sleeping.
These are things are lets face it, basic and usually come with a negative consequence but for me they can do the job and give me anything from a few seconds to hours worth of lesser OCD which can be a life saver quite literally.
Long term: Games, Books, Shows, Guitar (any instrument really), Spending time with the person you love.
Hobbies really but more something you can try your best to focus on and try to get lost in. Unfortunately my OCD has now stopped me from reading books almost entirely, same with instruments.
Long term are really "general" ones but seriously if I did not have any hobbies that were able to take away my mind from my OCD I'd be dead a long time ago.
Sorry for the long post, hopefully if my post wasn't helpful then others have been. OCD is horrible and I am sorry you have to suffer I hope you find a way of dealing with it because you deserve to live a life without it.
