Because you are only 17, you cannot be put out of your home by your parents unless they go through the legal system to do so. You cannot be out on your own, homeless. Try to go back home and work things out. Can you call your mom? She must be worried sick by now. Can you locate your father? If you cannot do that, go to a relative, an aunt, or uncle if you can, someone you trust, but seek help from an adult today that can help get things worked out. Is there a guidance counselor in school you can speak to? Sometimes a family doctor can be of service to steer you in the right direction.
