My grandmother is in the hospital – her main arteries are clogged in her heart and they have to do surgery to fix it. She is trying to decide if she is doing the surgery, which because of her refusal to take a blood transfusion is very dangerous (doctors are giving a 50/50 chance) or leave it and within three years they will completely clog and cause a fatal heart attack. If she does the surgery, it will be within the next few days. Could use some vibes for her. The surgery will be a quadruple bypass, with no ability to put blood back into her and she’s on a lot of blood thinners. 
And my mother is in a bad place, she is given control of saying no/yes to blood transfusion once my grandmother is under. So if the surgery goes badly, she has to be the one to tell the doctors not to try to save her, because she is the one my grandmother lives with and trusts not to be selfish out of her kids. I can’t imagine being told they can save her if you sign a paper and having to say no.
