How can i stop my dad from putting every1 down and being so judgmental?

The fact that you completed school and college through all that **** is very admirable. You should find help for yourself to control the more disruptive behaviors so that life is easier for you. But there is nothing wrong with how you feel. Some parents can really be . Best solution is to move out maybe get a roommate and live independently for yourself. nobody will have the right to criticize or make judgement about you then. It's a pretty great feeling. I did it to because of my mom and now I don't have to really pay attention to what she says anymore. Find your Strong. Good luck!
