I feel the same but...my 74 year old mother when she got sick put up so many road blocks with doctors it is now impossible to force blood....it's the most frustrating difficult time ever. And your other family support her. Not taking blood will kill her 20 years early but you really have no choice but to give up and let her die, this is very sad it breaks you.
I hate this Watchtower monster eating up the lives of our families in God's name.
