Green-orange,

it's so completely fantastic that you care so much for your future mil, and are patient with her right now when she's obviously not in a good place. Not too many daughters in law are like that, so hopefully when she's better, she'll recognize that.

Being so new to this forum and dealing with my own dx, I can only tell you that one of my huge issues is travel of any kind. Being out of my own home and routine always sets me down a dark path for a while, so I have to be really aware of how I'm reacting to things while I'm gone and for a while after I return. Since she's visiting you at the moment, there may not actually be a whole lot that you can do to minimize her stress, other than be patient with her when she seems to be the most ill or acting out.

Again, you're doing something really wonderful for your partner and for her.
