i keep remembering awful things i’ve done that i know i’ve changed from but it still hurts me so much i hate this

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..???

Hate myself for who I used to be. I used to sleep around. I drove drunk a couple times. I was careless. I’m so ashamed because it’s not who I am and especially not who I am now. I did it because I was lonely. And now I suffer not knowing if I hit or killed or hurt someone. This pain is just draining.

My real-events are terrible. I'm plagued daily by multiple awful things I did as a child / teenager (please don't downplay it.) I've grown into a better person, but the memories won't let me see any progress. It feels as if my insides are dying from grief and shame. How do you go day to day not picturing yourself as a monster?
