I'm young and inexperienced, but i would finish high school and apply for a college. you can dorm on campus.
Apply for a small job first, like at a gas station or fast food stop. you can either go to college and specialize in a high tech career, or if you want you can simply learn a skill. you could become a chef and cook for a fancy diner.
Dont give up, theres plenty of options for you.
