Cris, this sounds so hard. Can you figure out why she can't or won't drink? Did you say her swallowing was getting too hard? I wonder if there are other ways to hydrate, short of tube or IV. Would a straw be easier? Jello? Warm broth? I have no experience... just thinking someone must know!
Even though she is not presenting with end stage symptoms, she may be eligible for palliative or hospice which would certainly bring all of those comforts to her care. I read a lot about hospice services recently and (you probably know this, I didn't) a person can be in hospice if they qualify by being expected to die within 6 months, BUT you can go in and out of hospice. You go in when you need that care. You come out if you need therapy like more temodar. But even Avastin can be given as palliative care. Also, if a person survives the 6 month window, they can re-certify her for hospice again... at least the hospice group here is very flexible.
You know I don't mean to say that her time is up. But it seems like for her comfort there might be expertise in certain care settings that would really help both of you at this time.
When will you have a better sense of the tumor's status? It's soooo hard to just breathe through these long days.
Sending love and serenity ~
