Please let your friend know that my heart goes out to her and her daughter and her husband, who I am sure is sad to leave his family behind.
Your friend's family needs a lot of support, especially the daughter. She needs to be told in a gentle but very matter-of-fact way. She needs to be able to ask questions and understand what's going on. It's very important that she gets a chance to say good-bye to her father. Her mother may not be the best person to tell her. She is probably overwhelmed with her own grief and may not be able emotionally to be straightforward about it. Maybe a family member or compassionate nurse could be a help. Often the hospital chaplain is a great person to ask for help.
Tell her that hospice would be a big help. She has to choose which hospice carefully, though. I've been a hospice volunteer for years and its tragic the way its gone downhill since the big for-profit companies have taken over. Ask for the hospice chaplain and go for the hospice that has a chaplain that you like. Also ask for a hospice that is committed to after care for the family.
Death is a sad but powerful part of life. Deep emotion can serve to draw people together and strengthen the bonds of the heart if there is open communication and time for grieving. It's tragic when a death in the family causes people to drift apart and shut down their hearts. Gentle presence and compassionate listening really helps keep the heart open.
I pray your friend and her daughter have all the support they need to grow closer through this very hard time.
