Hopefully she is now comfortable & does not suffer as she goes through this phase.
Hospice care is tough to handle emotionally for all, but the care givers there are really compassionate & do what very few are willing or able to do.
I had a friend in a similar situation last year & he insisted on going home to pass.
He got to leave the hospice facility, & lived another 3 months at home as he wanted.
God bless her and you, as well as your loved ones in this difficult time.
