I am responding to your question, not because I can answer it, but because I don't want you to think we don't care by not responding. Your's is a question most of us have to answer for ourselves at some point. And there are as many answers as there are people and all of those answers are right.
Those of us here are obviously still alive and those who have a similar prognosis to yours are probably busy with their own preparations. There are a few folks here who were caregivers for loved ones who have died from cancer and they might be able to respond with the end of life experiences they went through.
Wishing you and yours all the best in the coming months.
