prayers needed

My grandmother is in hospice. She has been for a couple weeks. I flew in (thanks to my wonderful maternal grandparents) over the weekend and was able to visit with her one last time. Yesterday my family called and told me that she wasn't expected to make it. Miraculously, she is still alive as of now, but i'm beginnning to believe she would be better off passign quietly. Is that wrong of me? I don't know if she's comfortable, and I don't want her to be in any pain. Her breathing is a bit more comfortable, its true...but this weekend she was so miserable I couldn't stand it. I don't know what to ask for prayers for, but please keep my family in your thoughts
