How does one stop ruminating with Real Event OCD? It's so incredibly difficult right now :(

just wanted to see if others struggle with real event ocd really kicking their a**. i feel like my mind is a constant battleground of every mistake ive made and they feel so huge and life altering to me that it’s hard to continue going on in their wake. just wondering if anyone else feels this way too.

I've been doing well the past month in cutting down on compulsions and have been feeling better however, last night I had a set back that carried on into today. I had gotten very poor sleep (4ish hours) and then something triggered my memory. I think with the sudden anxiety spike and lack of sleep I didn't have the strength to ignore my compulsions. Last night and today I've realised I've gone back into rumination and mentally reviewing the event excessively again and comparing my situation to other people's, but most of the times that I start going down these rabbit holes I don't even realise I'm doing it? Also been fixating a bit on the fear that I've ruined my progress and that I will fall back into the deep end of it all again, that I have done so much work getting myself out of, although trying my best to not be too discouraged. Does anyone have any advice on how to deal with rumination more specifically?

Anyone who struggles with real event, rumination, and guilt. Please please please tell me your tips and tricks and maybe some words of encouragement.❤️
