I feel very bad about my history with animals

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.

my cat was smelling my other cat's bottom so to get him away i like quick "slapped" with the dorsal of the hand on his face and i got afraid that i did too hard so i compulsively did it again with similar strenght that i used to check if he was hurt and i regret it, like it wasn't a hard slap meant to hurt, but i did that impulsively and maybe i exceeded a bit over the limit in which it doesn't hurt. like he definetely reacted but i don't know if he was hurt, like he reacted in the moment but nothiny else, and he's lovey dovey. i dont think he was hurt but i feel bad. because if i did it once as a mistake i shouldn't have done the same thing again. i feel like an abuser. there are many things that are happening to me and im getting overwhelmed and i dont know how much longer i can hold on. because one thing i can't do is to forgive myself over mistakes.

I feel like a really terrible person right now, I keep replaying this, and no matter what I can’t remember what happened, it’s like my brain is purposely not letting me think about it. Without wasting any more time, I’ll get into it. Basically, I was at Walmart, and looking at cards with My Dad, I saw anime ones, took pictures of them for my sister, even ones that were anime kids, because I did my best to ignore it, so I looked at a Hunter x Hunter card, I stared at the black haired kid, being all like “ I’m glad I’m not having any thoughts about this, I’m glad I’m having normal thoughts and not thinking anything” I felt happy, then as soon as I looked at killua (white haired kid), everything collapsed. I don’t know what happened, my brain won’t let me remember. But I’ll give bits and pieces. I think that I had false attraction, and something in my head, said “oh, I wouldn’t mind being attracted.” “He is attractive, and I’m attracted to him.” “I remember a girl thinking he is attractive and he is” “ It’s not wrong to be attracted” “ I don’t care about his age” .. something along the lines of that, and now I’m panicking super hard, because I’m worried if I said those things, I feel like I ruined my life that I’m a pe//do and deserve nothing, idk what to do, I feel terrible… I remember when I was having the intrusive thoughts, I was panicking and was worrying, but it kept playing out, and I kept hearing things talk, it was drawn out too long, that now I feel convinced that I was saying those things, I tested it too, and I can confirm that I didn’t say that, but why am I still not convinced? I know I wouldn’t say those things, I was hoping the complete opposite would happen. My brain kept making me feel like it wasn’t wrong and it was okay. Maybe that’s why I’m so convinced I did that. I’m just spiraling super bad right now, I don’t know what to do or what to think, I don’t know if I said that or not… even if I did test it, I genuinely just feel like I said it, and I wanted it, because I still feel uncertain, I still feel like I said it, part of me just wants to be like oh I did and so I can move on, not because I agree with it, I just don’t know what else to do… I’m really scared.
