The best way to deal with that is to live in a fully conscious, compassionate, loving way. Don't wait until you're on your deathbed to recognize that this is the only way to live.
Everything that gets born dies.
Dying is only one thing to be sad over... Living unhappily is something else.
The little things, I can obey. But the big things - how we think, what we value - those you must choose yourself. You can't let anyone - or any society - determine those for you.
