Self-forgiveness

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?

Hi everyone, I’m new here, and I wanted to share my experience. I’ve been struggling for over a year now on obsessing over a mistake. And the rumination of the mistake I made has been overwhelming and exhausting in those two years. I feel like such a horrible person. At the time, I didn’t realize what I was doing would affect me so much. When I realized it was wrong, I just said I’ll never do it again, and I moved on. But then months later, I was reminded of what I did, and I felt like I did the worst thing in the world, and that my life will never be normal again. And ever since then, it’s been a constant thought. And it’s exhausting. I have been able to open up to my family and a close friend about it and their reactions were so nonchalant compared to what my brain has been telling me. They say it wasn’t even that bad, and that I shouldn’t be beating myself up. I tell them how badly I feel and they just act like it was nothing. I thought that would help, but my brain continues to tell me how horrible of a person I am and I obsess over this one mistake I made two years ago. I’ve learned from it, I’ve moved on, I’ve opened up about it, I’ve gotten reassurance, but yet it still eats at me. It’s constant some days. Where all I wanna do is lay down in a corner and never leave. I feel like my life will never be normal again and I’ll never experience happiness again. Whenever I smile or feel any type of joy my brain tells me to stop and reminds me that I’m a bad person and I don’t deserve to be happy. Even though everyone tells me what I did wasn’t even that bad. And that it doesn’t make me who I am. But guess it’s not enough and I’m really running out of options.

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.
