Aurora and DARKEYED9,
Be patient. Finish high school and get some college education. Get your family to pay for it if you can. Or learn a skill which pays well. Talk to some job counselors in YWCA or some college etc. It may take some time but you need to prepare yourself for independence. Don't do something out of anger or panic.
Also. Remember, you can have a job and be independent, but you may or may not, be able to live at the level you were accustomed to as a minor who depended on your parents. You may have to do without some things, like internet when you first start out. But if you care about your independence, you'll go without.
