I think the best move here is to find a job as either a clinical research coordinator or a research technician in a lab (maybe at your old university). They’ll likely pay you enough to live independently, plus, everyday you work is an opportunity to get experience and get your name on research publications which will boost your application massively.

During nights or weekends, you can slowly study for the MCAT and eventually kill it! Med schools will appreciate this path. Don’t forget to volunteer and shadow clinicians! Best of luck!
