Who owns the house? Is there a property management company or a landlord you can go to? Typically, in a lease, there are rules for how many people can live in the house. In the meantime, keep what is yours in your room, whether it's the couches, tv or dishes, etc. You own them, you decide who uses them. Is there a lease? Can you get out of the lease? Can you find someone to fill the rest of your lease?
