The stages are summed up by Dr. Elisabeth Kubler-Ross . She realizes that all people may grieve differently, but mainly all people will go through these stages during their process. Denial and Isolation are usually the first reaction toward the grief process. Because the person is trying to ignore the present, you must realize what they say or do is just in reaction to their lost. While supporting the individual you must listen, be nonjudgmental, and to not take anything personal.
Anger is the next step and possibly the hardest to deal with.
They will question everything to their family and friends and might question their religious beliefs. The best way to deal with this stage is to not allow their reaction get to you. After the person vents out their anger, he or she enters into the bargaining stage. They will promise to do better if you allow that particular person to live. They feel in some way the passing of their loved one was their fault.
