I have a really hard time getting over things. I used to be a lot worse and would bring things up all of the time, but I've realized that thats kind of ridiculous and unhealthy to literally any relationship. So, I still have the thoughts but I don't express them. For example, things that happened months ago in a relationship (whether it be with a partner, friend, family member, etc.) will suddenly pop into my head and I'll be enraged by it as if it just happened.

Does anyone else have this problem? How do you deal with this?
