Get me out of this hell!!!!!

I can't take it anymore. I'm 21 years old and apparently I still can't make my own decisions at least thats how my parents treat me. I need to not live here anymore but I can't afford to move out. I want to get out. I'm sick of not being happy, I'm sick of crying, I'm sick of living my life in a constant state of depression and hiding from everyone. I can't tell anyone how I feel because all they tell me is it will get better. I can't tell Nick because then he will be worried about me and thats the last thing I need. I JUST WANT OUT!!!!!! And no none of this means I'm going to hurt myself, I just don't know how to fix it. I want it to be thanksgiving so I can be in New Jersey and not here with my family.
