Few days ago, I drank so much I became blackout drunk. While I’m drunk, I go around hugging people and put my arm around peoples shoulders ”bro like”. Not in a romantical way. This time, I think (I don’t really remember), I either hugged or put my arm on a 15 year olds shoulders. I’m 20 myself and suffer from POCD. I asked a girl that was with me the entire night, if I did something inappropriate, and she told me she and the 15 yr old was pretty much the entire night with me and I didn’t do anything inappropriate and it just seemed I had a good time. The reason we were with the 15 yr old was because we were at a family friends party and we were put in the same group (there were games at the party). I have a very slight memory, I believe, of someone putting their hands on my waist, and I think it’s probably from when I maybe put my arms on someones shoulders, and I’m very scared it was the 15 yr olds.
I’m engaged, but my fiancé wasn’t at the party. I haven’t told him about this, but he is very well aware that I hug people and cling on people while drunk. I told him I started hugging people and that I was in the same group as the 15 yr old. I guess he can figure it out that I maybe hugged a 15 yr old. I talked to my mom and brother about this, and both of them believe I did nothing wrong.
My brain is imagining the worst scenarios. This whole thing has made me suicidal again.
