i’m scared i’m. horrible person

I am so scared of everything .Of my thoughts.If I am a good person.Years ago I didnt help a kid who was in danger.Since then I started to have terrible thoughts :( i am so terrified.I still have these thoughts and I am scared it means something about me .I really dont want to hurt anyone and I want to help that kid now but idk how I can now.Also I am scared I betray everyone.I still have terrible thoughts and when I am with someone I care is worse...idk why.For example I started to talk with a collegue and he is really nice to me.I told him some things abt me( not the intrusive thoughts) and he was supportive.I have no idea if I will tell anyone abt my thoughts..and bcs of that I feel like I lie to them and betray them.I really want to enjoy my life and be happy and support people( especially because I didnt help that kid then).I want to live up to my morals now but I feel like I lie and manipulate people bcs I am a monster.Is this normal? To feel this way? What can I do? What if I am my worst fear and just cant accept it?!

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 cheated on my bf, never thought i'd ever do it, i didn't mean to, it just happened, and i feel terrible about it, as i should, and now im not able to ever move on, even tho he wants to fix things, and now im prob just using rocd as an excuse to cover the fact that im genuinely just a shitty person, i hate that this a part of my identity now, idk how to come back from this
