My mind is arguing

Does anyone feel like they’re fighting a war inside of them? I’ve slowly opened up to people about my past and things that happened ( I never thought I would ) but at times, I value truth and honesty and wanting to be a good person and this is something I just want to let go of because I’ve suffered with the guilt and shame and regret but my mind keeps on dwelling on it and bringing it back. Like I’m a fraud. This implies to all my mistakes that I’ve learned from. I normally tell my mom things but I don’t want to tell her these things. I love her and don’t want to bring shame upon my family or for this to be brought up over and over again. I did stupid things without logically thinking and I have the best mom ever and she trusted me with things when I was younger. I made mistakes with that trust and it makes me upset. I now feel like I’m ideally the “ideal” kid for my family and I wish to stay like that no matter my age. I’ve been trying to mange with my childhood mistakes. The shame and guilt. I’m trying to be a bit more compassionate but there’s always the thought that scares me, what if I was really evil? I used to hate looking at pictures of myself when I was younger but now when I do, I finally realize what they meant by “you aren’t your worst mistake” because I’ve done good and I’ve also screwed up. But I feel like I’m fighting a war with myself because I value justice and truth and so but I don’t even wanna talk about this or bring it up and my mind keeps targeting it and it’s exhausting.

Why is my mind saying I should say my thoughts out loud and that it will be ok, I don't want to because it goes against my beliefs and it freaks me out because my mind is like you've done this and this an other bad things this can't hurt you, saying it will give you peace and it just randomly started yesterday and idk what to do. It's like I have no will power to want to stop it's like my mind wants me to say it and idk what to do.

sometimes my brain is thinking of every thought you could have all at once and it makes me insane and i keep telling myself in my head to shut up and i try to stop thinking but it doesn’t stop
