I just helped a young person your age who is making straight As in school get all the funding she needs to declare herself independent of her alcoholic and addicted parents and afford to finish school and live on her own. Go to your school's financial aid office, ask them for a form that you are not a part of your parents' income, ask your dad to sign it, apply for FAFSA, work-study, and anything you're short of, you most likely would qualify for some on campus scholarships because of your grades. If you're still short on funds, you may also qualify for a small student loan to finish out the year. I recommend you get a roommate or two or live on campus if possible where it can be inexpensive. You don't have to live in that environment with your parents. And you can find some good Al-anon groups in the area in Memphis. Lots of good ones there.
