I don't have any sage advice to offer here, but if there is any way I can help let me know.
When I was much younger I did have a bad situation that I decided to separate myself from. I was lucky enough that the someone I knew let me stay with them until I could get a place of my own. Maybe without realizing it right now, you do have someone you can reach out to that can help you through this. People can be very kind if you reach out when you really need it.
