Here's an idea....how about asking your Mom's doctor to write a letter stating that her health condition does not lend to having anyone living with her for any amount of time. He does not have to explain what her health problems are (HIPAA regulations and all). That way, you would be getting some support to back you up...and from her own doctor no less!

It's worth a shot I think. I do so hope you can get through this with little hassle. Family can really suck the life out of you sometimes. I'm so sorry you are having to deal with this situation.
