This is a predicament for you. How about looking to get a place with a roommate that can share the rent and other expenses? How about asking a friend to move in together? Is there on-campus housing you could get? Maybe you could speak with a financial aid officer and see if there are options for you in that realm?
I think I would look into anything and everything before making a decision to move back home where you know there will be issues. I would keep home as a total last resort.
Open your mind to different possibilities.....talk to others and network and see what you can find
Wishing you well!
