Five Stages Of Grief: Kubler Ross


1.Denial and Isolation.
At first, we tend to deny the loss has taken place, and may withdraw from our usual social contacts. This stage may last a few moments, or longer.
2.Anger.
The grieving person may then be furious at the person who inflicted the hurt (even if she's dead), or at the world, for letting it happen. He may be angry with himself for letting the event take place, even if, realistically, nothing could have stopped it.
3.Bargaining.
Now the grieving person may make bargains with God, asking, "If I do this, will you take away the loss?"
4.Depression.
The person feels numb, although anger and sadness may remain underneath.
5.Acceptance.
This is when the anger, sadness and mourning have tapered off. The person simply accepts the reality of the loss.

Grief professionals often use the concept of "Grief Work" to help the bereaved through grief resolution. One common definition of Grief Work is summarized by the acronym TEAR:
T = To accept the reality of the loss
E = Experience the pain of the loss
A = Adjust to the new environment without the lost object
R = Reinvest in the new reality
