Does anyone have any tips for living with the unbearable guilt?

What to do when we feel guilty about our ocd checking and compulsive behaviors?

I know I shouldn’t and I’m trying not to ask for reassurance but how do I deal with this when I made real event mistakes in childhood? I’ve opened up to my cousin about this who’s an adult and believes that kids can be influenced at a young age and mimic things that they see and friends and my therapist. They all see the good in me and my stupid childhood mistakes but the guilt is very strong and even though I’ve opened up It’s telling me to open up more and more and I don’t know what else it wants from me.

I need to find a solution fast to stop this way I’m living but I don’t think it’s possible, I’m in a constant state of pain from being tormented with guilt and warped memories. I know some of the memories to be true and some are all jumbled together so they get warped. It kills me to not know if I’m evil or not , I’m always thinking of the bad things I did when I was like 13 and didn’t know much about what’s truly right and wrong. I just feel like such a bad bad person , I don’t want any form of relationships at all because then I’ll have to confess everything bad I believe I’ve done or else I’m lying to them about who I am. I don’t really want therapy because I’m not confessing these memories or thoughts to a stranger especially because I’m only 16 and very socially awkward so I won’t be able to open up about this at all. I keep most of all of this in secrecy because I know nothing truly gets rid of the guilt. I also don’t allow myself any sympathy anymore because I just think I don’t deserve that either because evil people don’t deserve any empathy , it’s so hard to live with this. I just needed to get this off my chest since I’ve got no one to talk too
