Your dad does sound like a tool. I concur with the advice above to finish high school. College is not the only way to build a life. But you will need training for some kind of work. Some jobs train you as you go along. I'm a huge fan of community colleges and vocational technical schools that are public. (The private ones cost a fortune.)

Once you can support yourself, your problems with your parents will be 90% alleviated. Aim at that. Being good at getting along with people is a huge asset. Employers value that above a lot of other things. Try to get a part time job now, even if it's only two days a week.
