Doug I can appreciate how committed you are to Judy but I have to tell you something from experience. My wife was sick for quite a while and I was her primary care giver. It got to the point that I was getting sick. I realized that if I was sick I was no longer any help to her. I called her sister , my daughter and my son and we set up a schedule that allowed me to get sleep at night. We did that for the rest of her life.
Please reach out to people who are there to help you. I compare it to what they tell you on a plane “ when the oxygen mask drops if you are with someone that needs help put your mask on first” . If you get sick you won’t be able to help Judy.
Rhode island’s motto is Hope. Remind her where she is from.
All the the best, Ernie
