...I would call my lawyer and make it clear that if he or she didn't hear from me on a defined schedule that he should start looking.

Then I would sit down and think of my options, assuming that I had some. Is it possible that outside help could be an approach? Could you make it if you were living alone with such help?

I have long maintained to my friends and spouse that if they one day find me dead lying in my kitchen floor in a puddle of my own filth that they should give a great shout of joy as that is my desired ending. Each of us certainly has their own vision, of course. But we should make those decisions ourselves to the extent possible.
