Just tell him you are looking - that's all. He'll have to think of how he will rent out your room with such an ill woman as a tenant....

If you do find a place (you only need one, and it's out there somewhere!) ask your landlord about his not keeping your security deposit, if you had to pay one. That way you will have a little $. Maybe he knows another landlord that would be reasonable?

I am sure your landlord is not happy about the situation either, as it places his business in danger.
