Just because you have been damaged emotionally, does not invalidate other people's emotions. They are quite possibly feeling the lowest lows of their lives -- even if that low is a mountain pass versus your death valley. They still deserve respect in grief, even if overall they have had a wonderful life.
Someone with living and attentive parents, who lived in good health to their nineties, lived in their own home, in a well-to-do country, where their child came to visit them, in their own car, in good weather, etc... what more did they expect to happen? This is the best outcome by far they could expect from life. They've won the lottery, what more do they want?
No. You completely misunderstood my point. I'm not "emotionally damaged". Overwhelming majority of people on planet Earth don't have it anywhere near as good as the people in OP or a bunch of people commenting here about their quite alive and quite well-to-do families. With all that happened to me, I'm still among the few percents who has it relatively well. Vastly more people in this world will have it worse than I have.
The entitlement of people crying about how bad they have it, when they are among the fraction of a percent of those who have it the best it can possibly be is what's so disgusting.
