I am sorry to hear about the seriousness of your illness and admire your for dealing with it so openly.
Since I had death and illness of a close relative lately, I would ask you to think of two things:
- Give full powers to someone to deal with your affairs when you cannot
- Make sure you have a current patient's provision
From the way you are approaching the end, I am pretty sure you have already done so. But I just want to make sure. It can really take a lot of burden from your daughter and other relatives.
Making a live-or-death decision for a loved one is really, really hard.
Concerning your daughter: you may want to leave her letters (one per year until 18) describing how you experienced live at her age back then. Just let her know how you felt, what moved you, what you loved or hated.
