Jenn-

I'm also around your age, but have been independent of my parents since I was 19. I came from a chaotic home environment, experiencing pervasive physical/emotional abuse. We often have a compulsion to repeat our childhood experiences in our adult relationships. I've struggled with my anger for years (not physically violent) and through therapy, have come to realize that much of that emotion is connected to the physical/emotional abuse that I suffered as a child. If you have the resources, I recommend seeking therapy to explore these aspects of yourself. It's been a godsend for me.
