I tried to respond to your message but could not so thought this might get to you.
I know how hard the waiting can be and the decision your husband has made to discontinue treatment. Each person is different but I can share what helps us, Hospice, having someone to talk with, be it the Doctor, family or friends. You and your husband must have questions about what the future holds and how it will all take place. Please try and find a good support system and don't be afraid to tell them your fears and what you are going through. Remember you have to take care of yourself too.
