How often do you have the urge to punish yourself for your past mistakes?

I (20M) have this urge very often, because even though I've done my best to improve in order to not make the same mistakes again, I still feel like I have to give myself some form of punishment . Even my family tells me that the damage is already done, and there's nothing I can do but to move on, but how can I move on when I was the one who've caused the damage? Sometimes I feel like my family holds grudges against me, they don't show it, but I know that they at least have resentment towards me for the things I've done.

I don't know, maybe I'm just overthinking that, but yeah, that's how I feel almost everyday. However, I'm willing to prove that I do have potential to change for the better, and not for the worst.
