@dbaplanb What a horrid situation! It sometimes happens we can't get another caregiver to help out so John and I do 12 hour shifts those days. It may not sound like much but for this type of caregiving, anything over 4 hours starts to be a real strain. Full-time care is WORK. And I too would rather never hear anyone tell me that I should take care of myself too.
You are really alone in so much of this. Thinking of you.
