Less me be me while I am living with my parents

I am an artist with a problem. I am told that I am not allowed to express myself the way I that I only know how to. Its isnt writers block or the fact that I cant hold a paintbrush, its that I cant get away from my parents and their rules, and I believe that once Mom and Dads son or daughter reach a certain age then they can do whatever the hell they want and no one can f****** tell them otherwise, even if they are living in their house. I want my parents to stay away from what I do and not come near me when I am trying to learn how to express myself creatively, and most of all. I want to stay out of my college dorm room. If my teachers and my pears say that I can do what I want now because the law says I can and my parents have a problem with it because of morals and religion , then I cannot support that. My own children are another story but I want to be me, because I know I have a right, I have a constitutional right. The first amendment says that I have a right to freedom of speech and expression and am exercising my right by signing this petition.
