Paula,
I am so sorry to read about what you and Jim are going through, but I have to say I think you are both totally amazing your guts and determination to do all these trips are truly inspiring. Not at all surprised you are so angry and frustrated - I often get like that with Chaz in circumstances that are not nearly as severe as what you have been through. Have to say although I feel for you terribly, Jim sounds like an incredible man.
Words are inadequate but I admire you enormously.
Cathy
