I'm really depressed

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’ve posted something vulnerable here before and I’m trying to ride out the wave of reassurance where it’s getting at me and I’m scared of sitting still with nobody to talk to about this at the moment I genuinely think it would be easier if I wasn’t around. I view my friends as pure compared to me and I’m the most impurest. I feel like this would do a favour to stop being here I don’t know what to do, I really don’t know. I’m literally alone in this and I’m getting tired. How do you deal with stupid choices that you made as a child? I’m trying to be understanding of past mistakes but it’s gut wrenching to try and accept to say and admit you did it knowing you’ll spend the rest of your life with that guilt..is there another perspective to this..???

I’m really struggling with real event ocd at the moment because I feel like no one else has done what I did so I’m the exception. I spoke about this already here but I’ve literally been crying every day I feel so hopeless at the moment I wish I could just go back to the years I spent doing this thing and stop myself because my life could have been so much different now. I hate myself so much because I cannot forgive myself. What I did isn’t morally bad it just does not align with my current identity so I really struggle with accepting myself because of my past mistakes. I wish so badly that I had a friend who went through the same thing because I feel so alone
