Dear Karen,
the first thing I did after my Dx was prepare for my death. I got a living trust, will, advanced directives, etc. It was just one less thing to deal with later and once it's done it's done.

Death can be very "inconvenient" for the caregivers and frightening as well. Your aunt may just be venting and trying to give you a reality check here. Like we all respond differently to treatment, we all handle our death in our own unique way. Your dad probably already knows the dire straights of his situation and wants to impact you as little as possible.

It is sad but true that many doctors optomistically overestimate survival time.

With the support of hospice your dad will find peace and quality of life that will ease this "inevitable" process and give the family as much quality time together as possible. Don't waste it. Say what you are feeling.

Staying connected with your dad, asking about family history and his life will be extremely important as time goes by. These will be the memories that you will always have. I would also suggest journaling this part of the journey as well.

I lost one parent to a massive heart attack and the other through a short (one month), from Lymphoma, in hospice (at home). Death sucks whatever form it takes.

Thank you for your caring and prayers and likewise we will keep you, your dad and aunt in ours. I can only wish that I had a daughter like you. Your dad is a very blessed man.
