Why is this bothering me so much?

Everyday I wake up, all my mind makes me think of is the stuff I’ve done in the past, like all day I’m in a constant cycle of judging who I used to be and it hurts so so much. I wish I never thought to do those things, I wish I had been more mature than how I was before, it’s really lowering my self worth and I don’t think I’ve ever felt this miserable before, like last summer was the worst because I was dealing with this shit, I about almost ended my life over it, and I thought it would get better, which it did, but it didn’t last but for a while. As soon as it became 2025 I was going through it again, having constant cycles of “I’m a good person” to “I’m the worst person imaginable” and I’m so sick of it because I just want to feel like the good person l like to imagine myself to be, but I can’t because of shit I did in the past that I obsess over. I’ve cried and screamed so much over it and it seems like it will never leave me.

Does anyone deal with rumination with their childhood past mistakes. Deep down I know I didn’t know any better but then I start having thoughts and it gets worse after that. I also recently have dealt with death in the family, started my period, started college and just moved to my own apartment this last month. :-/ I genuinely just wish I could let go of my past I feel like I could be a better person for myself mentally if I could just let it go.

So I was at a family thing yesterday and my ice was bothering me and I kept washing my hands and my family noticed and started making fun of me for it and it was like non stop it made me feel really alone especially since they clearly know something’s up but they just make it worse instead of at least trying to help😕
