Alcohol making OCD worse

I’m having the need to confess that I was unfaithful to my girlfriend (even though I was not) because I drank too much Saturday night and don’t remember every single second from my evening. My OCD immediately goes to that I cheated on my girlfriend and I need to confess my sins. I know it’s only OCD, but the thoughts are extremely strong. Any suggestions? Thank you, community.

I feel like the worst kind of person and I am ruining my husband. I don’t know how I’m going to be able to change.

I know the truth deep down but I am just doing compulsions to try and convince myself that I have OCD. I try to look up and find things exactly the same and me in experiences how I feel and everything else and it becomes worse when I can’t find the same person as me. I know people do compulsions to make sure they love there partner but I feel like I do compulsions to CONVINCE ME it is ocd
