Bro OCD is just bothering so much

For like an two hours I've been feeling germs and dead cells on my face and now I'm touching my face every minute, basscisally scratching it but without my nails(using my fingers only)plus there comes the need to touch it in specific places and and specific amount of times
Thankfully it's stopping currently and I don't really feel it right now but dealing with it for two hours is just awful
