According to Elisabeth Kübler-Ross, when we are dying or have suffered a catastrophic loss we all move through five distinct stages of grief. 

We go into denial because the loss is so unthinkable we can't imagine it's true. 

We become angry with everyone, angry with survivors, angry with ourselves. 

Then we bargain. We beg, we plead, we offer everything we have. We offer up our souls in exchange for just one more day. 

When the bargaining has failed and the anger is too hard to maintain we fall into depression, despair. 

Until finally we have to accept that we have done everything we can. We let go. We let go and move into acceptance. 

 we have a hundred classes that teach us how to fight off death and not one lesson on how to go on living.
