Can someone give any tips for getting over the back door spike?

Hey everyone, just wanted to post an honest update on where I’m at in my HOCD recovery. Right now, I'm stuck in what feels like a 24/7 spike — nonstop thoughts, intrusive sensations, identity doubts, and hyperfocus. The worst part? It feels real. Like I’ve “lost,” like I’ve accepted it, like I am gay. The thoughts don't feel like anxiety anymore — they feel like truth. I’ve been trying to do ERP, but the spike has been so constant I don’t even have to “do exposures” — the thoughts, feelings, and sensations are just there all day long. It’s like living inside an exposure. And it’s exhausting. BUT — here’s what I’ve been doing (and what I’m sticking to now): I say once: “These thoughts and feelings are welcome to stay for as long as they want.” I let the doubt, the feelings, the hyperfocus exist. I don’t check, test, or analyze — even when it screams at me. I live my life anyway — folding clothes, watching TV, eating, walking — with the storm in my head. Even when it feels 100% real. Even when I’m fully focused on it. I’ve stopped trying to feel better. I’m letting it all burn — and just not fixing it. It doesn’t feel good. It doesn’t feel right. It doesn’t feel like progress.

I’ve recently been having the spiraling intrusive thoughts coming up out of seemingly nowhere. Well not exactly nowhere, having some relationship issues but the thoughts will just randomly show up when I’m clam home reading a book.

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?
