This is so sad.. It sounds to ,me like your kitty is really sick and the least is she is severly depressed. I don't want to put a guilt trip on you, that is not what I mean to do... But it sounds to me that moving her anywhere would make her a lot worse.

I know you said you are kind of between a rock and hard place but is there some way you could use that pet psychic some are using here to find out if she is physically ill or emotionally ill.... or both?
