So sorry to hear about your sister. I wish doctors would not state such time frames. So many people go home, set their timers, and wait.
Is your sister active at all; able to get out and about? Is there anything she wants to do or see or hear or smell or experience? Anything is better than twiddling thumbs till the end.

"Life is a lemon and I want my money back!"
"No more turning away from the weak and the weary.
No more turning away from the coldness inside.
Just a world that we all must share.
It's not enough just to stand and stare.
Is it only a dream that there'll be no more turning away?"
