The gun is against your head and you are about to die. The survival instinct kicks in and you feel absolute terror. What if the gun is against your loved one's head? Your heart is pounding as despair washes over you. NO!!! This is unbearable... what to do? There can only be 2 very basic choices:
1) Pretend the world isn't really the way it is by deluding yourself death is not the end...
2) Try to change the way you think so you still see the beauty in life even when it seems unbearable...
