My heart goes out to you, your friends and their family. It is so very hard on the family & friends of those who get terminal cancer. I am so sorry.
If your friend choses to not continue chemo, Hospice can be such a blessing. My spouse did weekly chemo for over 7 months and then 3 treatments 3 weeks apart. There came a time, though, that my husband and I realized it was time to stop "treatments" and call hospice. It was such a blessing. They were there for my husband, myself and my 18 year old daughter. It made an impossible situation bearable and made us feel more secure in our home care. Also, they do offer bereavement services to my daughter and myself for 13 months.
God Bless you all, Laura
