I can't speak as someone who has been a Hospice worker but I can speak as someone with experience having Hospice come in for a loved one. Without Hospice I think my beloved Grandmother would have 'held on' longer than she did. They were like a 'permission' to let go, and we were blessed immeasurably by their having touched her life, and in that way having touched ours.
I can't speak to the logistics of making it work for you, but if you're thinking about it, I can tell you for sure you will bring a comfort to families who need a kind hand and a kind word at the most crucial juncture in their lives, as they help a loved one move into the next life. If you can do it, I wish you all the very best in making it happen.
