Feel like I’ve made too many mistakes

I’ve said and done so many hurtful things growing up, especially in elementary and middle school. I was very passive aggressive and mean for a majority of my life, and I’ve hurt peoples feelings. I’m no longer like that now, but every single thing I’ve ever done wrong replays in my head constantly, from the moment I wake up to the second I go to sleep. I know I deserve to feel the chronic guilt and shame, so I feel even more guilty pitying myself. It’s eating me alive, I’m so scared. I know people must hate me, and they have every right to. feel like I don’t deserve to have moments of happiness because I’ve taken that ability away from someone before. I’m not diagnosed, but this has been going on for years and I’m scared to talk to anyone about it because I fear they would look at me differently knowing I’ve hurt someone’s feelings. I feel like a monster. It’s ruining my life and I don’t know what to do.

I have sent nudes before when I was younger and I am really struggling with the fact that I have sent them because it makes me feel like I am such a bad person and I don’t deserve certain things. I try my hardest to be a good person and do the right things but I obviously have made lots and lots of mistakes. I cannot get over these mistakes I’ve made because I judge myself so hard for them and it’s making it hard to function.

I have made multiple mistakes in my past that lead me to believe im a bad person. thinking about them often sends me into a panic attack. i cant help but feel i need to be punished. i hate this feeling, what should i do?
