Luckily, (I think?) I've had very few encounters with the kinds of things that you're supposed to grieve over. In my life, the only deaths that happened near me were family pets, an acquaintance in grade school, a grandmother, and a friend's father, whom I had met only once. I went to all of the people's funerals, and cried a few honest emotional tears at them, but I think I was mourning something different than everyone else was.
At the funerals I went to, despite that there should be a difference between the death of a man I had seen just once, and the death of my own grandmother, I felt about the same and cried about the same amount. When I didn't use to be aware of my abnormality, I never thought about this, but now I realize that that's pretty damn weird.
I had no emotional attachment to these people, and I haven't missed them, but I wept nonetheless. I now know that I was really just depressed by the idea of mortality. I hhhaaaaatteeee the thought of dying; of everything including myself being completely temporary. I don't see much evidence for an afterlife, so for me, death is death and the end of my brain function is the end of everything. That's one of very few things that truly terrifies me.
I do wonder if the death of someone I see every day would be different, but I have yet to experience that.
How have you all reacted to this kind of thing?
