Rumination

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?

Are intrusive memories a thing? Because I have memories pop up throughout the day, usually regrets or mistakes from when I was younger, but it's almost uncontrollable? It sort of feels like I'm testing myself to see if the memories still make me anxious or something. I can't tell if I'm willingly thinking of them or if they just invite themselves in. They're just always at the front of my thoughts unless I'm really engaged with something else or out and about with other people... I'm trying to treat them like I do with intrusive thoughts, but occasionally, it's like I can't resist NOT ruminating on these past events. I try not to, but then that only makes them more persistent. I'm just curious if anyone's dealt with this or possibly has advice? I'm guessing I'll just have to sit with it. I don't think I've asked about this before, but I might be wrong lol. I forget easily 😭 I'll probably speak with my psychiatrist about this, too, but our next appointment isn't until August. She's not an OCD specialist or haver, so I thought I'd ask here, just in case anyone can help! 🤍

I've been told it's impossible to "push intrusive thoughts away", but also that rumination is a compulsion. What is rumination vs. overthinking? And how do I stop ruminating properly and healthfully?
