Earlier quoted context omitted.
I feel you, I also unfortunately have experiences with that. It has profoundly changed my view on living, especially how I want to be treated when someday I'm heavily sick. A family member in a coma takes a heavy toll on you, emotionally and financially. They are simultaneously there and not there. If they did not write down how they want to be treated you can never make a decision where you are sure what's right, or…
> For me, the decision is clear: when I'm not able to make my own decisions turn everything off and let me die. And what if you might be able to make decisions again tomorrow. Or the day after? Or in two weeks time.. ? These things are never all that 'clear'.
Edit: note this might be different for you. You are the only one who can make that call. You can also decide that you want to be kept alive as long as possible. But then at least your loved ones know that that's what you wanted.
