Imagine that the last thought that goes through your head is "No-one loves me."
Wouldn't it just be the same as thinking it any other time?
Not necessarily. Our destiny hasn't been filled completely yet, has it? Most of us are only teenagers, and we have at least say, 60 years ahead in our lives. That is a long time to be loved and to love back.
But say your 84, living in nursing home with no relatives left (you outlived them all? tragic.) Then you slowly die in a chair, and your last conscious thoughts are about how no one will be at your funeral, or you will be given state funeral paid by the nursing home, and you have no one to remember you with warm memories.
And then you realise, you have no way of ever changing and you left it too late, and that nice lady who lives down the hall, well, she's never gonna know.
There is more saddening things, but I don't feel like mentioning it.
