Question about gathering my death info

Hello all ? wonderful topic I know but I have a very difficult choice to make. Maybe hearing from some of you will help. I have very nearly finished with what I call my (dark humor) death box and have my funeral arrangements made. I should tell you that I suffer from an incurable illness that will take me from this world sooner than I would have wanted but that’s the way it goes, right? Anyway, of my two grown dtr’s the youngest at 46 walked away from us over a year ago and hasn’t spoken to either my husband or myself since. As far as we can tell it’s because we moved 5 hrs away without her consent, she thinks we moved to be closer to her sister - we moved because it was cheaper after my husband retired - and because we weren’t able to go to our granddaughters high school graduation because I was going thru chemo and my sweet dog had just became paralyzed in both hind legs. No place would take her overnight. Our 19 yr old granddaughter blames ME. They do not believe I’m ill. My question is, do I even need to tell them of my passing? I don’t want to and they have been written out of my will. My other daughter feels guilty. My husband is undecided. I’ll be dead but my daughter will obey my wishes. My husband I doubt. What do you think.
