Emancipation?

Hi, ladies! I am 16 years old, and I live in North Carolina. I'm a junior in high school. I would like to move out of my house soon. I'm about to get a job, and after that goes steadily, I want to leave. My mother provides a steady income and a car for myself. But I can't take living with her anymore. She constantly criticizes me over everything that I do. And I'm done with it. I do everything around the house, cook, clean, babysit my brother. I'm making all A's in my classes, and have a 4.0 GPA. And she always tells me that I'm not doing good enough. And that I should be better. I have homework every night, and she complains when I don't do one of her little chores for her. Even though she's the one who said grades were most important. She sits around all the time, while I'm working for her. I'm not trying to be a stereotypical teenager. But I can't live with the stress of college classes, a new job, and her being on my back all the time. She is extremely childish and talks bad about me to everyone, even in front of my face. And when I try to explain myself, in a civil manner, she considers it to be an attitude. And I keep getting privileges taken away for nothing. I have a place to go if I get emancipated. I was just wondering about the whole process, and if anyone's ever been through it. Thanks!
