How can i control it?

Whenever I get in an argument my mind blanks out cause I get so heated. When this happens it almost always turns physical. My family is a generation of violence and anger issues. In particular my mom and gf, I can't take their yelling all the time and I come so close to KO'ing them. But I don't I just leave and fight some dude to relieve the rage. I don't want to hurt them, what can I do bcuz it's get worse and worse
