Unless your parents are physically or sexually abusing you, you ought to go back. I remember when I was your age, and had similar feelings of unbelonging. It sucks and is tough.But your parents love you even if they find it hard to express or say horrible things and you guys keep arguing all the time. Sometimes when your parents are acting more like children, then you have to be the adult and step up by making allowances to avoid volatile situations and keeping a tighter rein on your own feelings. It's not worth the both of you feeling hurt and betrayed for the rest of your lives, you should make peace.
