I agree with above. Try to get into college. If you don't mind military service (USA), join a branch for the GI Bill. You'll also get into great shape, travel the world, etc. I recommend the Navy or Air Force, but that's me. You'll have a place to sleep, meals, exercise, travel, training, and build self-confidence. By the time you are 22, you'll also have money saved up and also the GI Bill waiting to help you with college. It's actually what I wish I had done.
Your father has ZERO say or control over you once you are 18. Good luck.
