First there is:

Shock and Disbelief - Denial

then

Pain laden with Guilt

then

Anger and Bargaining (blame)

then

Depression, Isolation, and Reflection 

circular, until...

A Turning Point

and then (time depends on external and internal factors)

Working it Out, Rebuilding

then

Acceptance

These steps are at times revisited over the same subject if they are reawakened by an event that reminds us of where we were when the whole thing started.  A photograph can do it.  A birthday. An anniversary.  A song.

If you find yourself in the first step of a personal crisis again, long after you were thinking it was dead, stop, ask yourself, "Didn't I accept this already?"
