Maybe I'm just feeling spacey, but I'm not sure if I ever heard of a person calling another ungrateful for wanting to end their life. Many other things, sure, but not ungrateful. It seems like something a mother would tell her child for throwing a fit. Your prompt did however remind me of a quote by David Foster Wallace I'd like to share:
"The so-called 'psychotically depressed' person who tries to kill herself doesn't do so out of quote 'hopelessness' or any abstract conviction that life's assets and debits do not square. And surely not because death seems suddenly appealing. The person in whom its invisible agony reaches a certain unendurable level will kill herself the same way a trapped person will eventually jump from the window of a burning high-rise. Make no mistake about people who leap from burning windows. Their terror of falling from a great height is still just as great as it would be for you or me standing speculatively at the same window just checking out the view; i.e. the fear of falling remains a constant. The variable here is the other terror, the fire's flames: when the flames get close enough, falling to death becomes the slightly less terrible of two terrors. It's not desiring the fall; it's terror of the flames. And yet nobody down on the sidewalk, looking up and yelling 'Don't!' and 'Hang on!', can understand the jump. Not really. You'd have to have personally been trapped and felt flames to really understand a terror way beyond falling."
I don't know if that applies specifically to your situation, but imagine, then, someone standing on the ground, pointing up to a person falling from a burning building and saying "Well would you look at that ungrateful person!"
