Ruminating about the past

I ruminated too much this morning and got distressing mental images (and confirmation) which sent me spiraling again. How do I stop thinking about this and how do I get back to myself? I feel destroyed.

With real event OCD, I don’t know if any of you feel this way, but do you ever feel that the past event(s) that you ruminate about or constantly obsess about are gonna come up in your future and just absolutely ruin you, that’s how I’ve been feeling for months, it just feels like impending doom, and I hate having to even think that my future would be ruined by what I did as a teenager, and I did some dumb things, that I regret so deeply, I just can’t stop thinking about that.

Due to real event ocd and past mistakes? I’ve been actively trying to work on this and try to accept and not pay too much attention to it but the confession thing has been bugging me but I’m also trying to accept that I don’t need to confess every single mistake I’ve made and we’ve all made mistakes Recently I’ve been wanting to work on myself and be more positive but because of my real events in childhood, I feel like I can’t live a normal life or deserve a normal life.
