The reason the concept struck me is that I had a friend who drank themselves to death, who was terrified of dying, knew (I think) what was killing them, but insisted to everyone who would listen it was some rare medical problem and they hoped for a miracle cure. After trying everything else, I tracked down the leading specialist in that rare medical field, and got my friend a consultation.
He said what I thought he would, as kindly as he could, but it made no difference at all. I walked away in the end, after years, because I couldn't watch someone kill themselves, who did not want to die, while asking their loved ones to subscribe to the story this was just a terrible, terrible, stroke of fate - a great, tragic mystery and there was nothing anyone could do.
I still think about the choices my poor dead friend made, and if they were choices at all. And I still think about the choice I made too. I always will.
