Does anyone else have no idea what their intentions are and feel like you are the worst person in the world

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?!

Just trying to accept the uncertainty and move on.... I don't want to be bad.... I want to be a good person.... But I feel like a bad person sometimes I get horribly disgusting thoughts when I'm angry and think the most horrendous things

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.
