agrees, they are just taking advantage of your hospitality. Honestly, I would either just do you and not worry about it. Or if the problem becomes big enough and you feel like they want you out, I'd make them buy me out of my lease (which I don't think they will if they can't afford anything).
and finally if it seriously this bad, I would talk to the landlord and see about getting out of there and see if they have any other options for you
