Am I wrong for cutting my parents off completely?

I've been at odds with my parents since I was a kid. I lost respect for them because they've done things and said things that you shouldn't say to your kid. It's like they get joy out of saying I'm not shit and they make me feel like my life is meaningless. At this point Im going to cut them off completely and never talk to them again. As far as my son goes they don't have a grandchild
