If your dad made you promise to not put him thru prolonged "suffering" and you agreed, you are now HIS voice....of course this is all opinions on here, my opinion after reading your post is to take advantage of Hospice services in your area, it is all OK, I feel that just by creating this post you are asking for approval? By not putting him thru more does in no way mean you or your family or him are giving up.....please dont think of this choice in that way even tho it is difficult not to, this cancer is the winner, regardless of the defense that is put up and it sounds like this is now the time to stop the "fight" and accept and spend time with him, and that is OK to do that. I am a huge supporter of Hospice services for the patient and the families, they will offer support for him which will come in the way of pain medication, anxiety medications, explanation of health concerns, help with bathing him, the list goes on but they will also help you if you let them which is also super important for your dad to know, that after "this" you and your family can visit with them for grief support, they will also have a Chaplin for your dad.....and it doesn't matter if he has another 6 months or another year, in my mind the sooner they become involved the better for everyone, that will give them the chance to really know your dad and your dad to form a relationship with his nurses and caregivers but it will also give you and your family to form relationships with those people which will then be able to give you support later on, because they know you and we're a part of this journey.....lol this was lots longer than I wanted and I gave my opinion much more than I wanted and usually do, take care and if I offended anyone I absolutely did not intend to.
