Cutting off family members ?

I am relocating in six months and starting a new life. i have lived with my parnts the past four ears and I am tired of the drama. They are constantly being negative and starting fights with me. I keep to myself and just go to school and work. My mother is overly jealous and petty and tries to take things away from me if I don't do what she says. If I do something for myself she gets an attitude and acts hateful. They've never supported me in my dreams and endeavors and I have alot of resentment towards them for how they have treated me. Should I cut them off completely?
