You may want to check out hostels that have a PT work/stay setup or IT internships that can provide housing. There are options out there depending on where you want to go but you may have to work hard with a job or two along with college. It's not impossible, but it is what many would consider difficult.

Just spend the time to research and make a solid plan and backup. If you can manage to leave your house amicably, you may want to consider how to strategically remove yourself on good terms. Wish you all the best. Keep asking questions!
