(((((wisewoman))))) this is so much you are trying to handle!

Having a spiritual base myself, I would suggest that you call in clergy. Not just for you, but for the teen who is dying. There is another realm and it's times like these that we simply MUST tap into it. Even if you have no church affiliation, there are chaplains in each hospital, and they often have words to say that help us on the way. good wishes.
