Ruminating about the past

I genuinely feel like the worlds most horrible person deeply for my past actions in childhood and general mistakes I’ve made. I feel like I shouldn’t be here or there’s no hope for me despite doing right ( trying to do right ) I’ve wanted to open up to my mom about things from my past but when I was talking to her about a situation that happened just to share, she was like “Thank God you’ve never done anything like that” But really my past mistakes are worst. It’s like I feel like I should disappear. I don’t know how to deal with the guilt and I feel horrible. I’ve made good and bad decisions but despite this being a long time ago ( which doesn’t erase my stupid actions ) I still keep bringing back into the present and I’m filled with guilt I genuinely think it would be better if I wasn’t here. I wake up think about my past things and I’m filled with guilt and shame that maybe I am a bad person and voices don’t stop, they keep telling me a lot of things that I start to believe. It makes me upset that I did something like that in my past and I try to be understanding but I can imagine the reactions of people and being condemned so much. I literally do this to myself every single day and it’s exhausting I don’t know how you guys can treat me with so much compassion and understanding. It really doesn’t feel real or like I deserve it. Like even on nocd, it makes me feel worst because I come across comments that say “as long as it’s not —-“ or something and I compare it to my past and I feel like a horrible unacceptable person.

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.
