I hate to say it, but she’s implementing her own hospice program. Deep in what’s left of her mind she does not want to go on.
If her religious attitudes permit, it’s time to talk turkey about the reality and whether the chemo is improving her life by extending it, or simply prolonging the misery.
And yes, this weekend is not to soon to go see her. It might actually be too late.
As to smoking … At this point it doesn’t matter. The cancer inside her doesn’t care whether she smokes or not. If it gives her pleasure, let her do it. If she wants to live on nothing but ice cream, let her do it.
To be sure, a better diet will let her last a little longer. Like 3 weeks instead of 2. But is that a good thing? Is that a net benefit for her? What does she think? Can she still think?
From this great distance it sounds like the one thing she doesn’t have is anyone willing to speak the truth and discuss the realities of the situation. If all the docs are mum and all the family members are silently hoping for a miracle while looking the other way as hard as they can, and Mom’s pretty well out of it all the time, … well … that’s how they pump $100K of chemo into somebody in their last month of life and render that last month a hell of drug side effects instead of the final farewells it could have been.
Difficult topics all. Been there, done that, have the scars. Good luck.
