It is necessary for us to get beyond this point. We must accept the reality of death and its permanence. Unfortunately the nature of death often makes it difficult to admit that a death has occurred. In natural death, anger, is not normally as severe as in cases of death by homicidal violence. Anger can be caused by the perception that others are not grieving enough, too much, or your loved one for leaving you and much more.
Denial is an escape from reality.
This was denial. I suppose denial is with me at this time too. Because I still wear the wedding ring that Kathy put on my finger in 1971. However, above all else denial is an unconscious defense mechanism characterized by refusal to accept the reality of death. Depression is a deep sadness at the loss often accompanied by hopelessness of the occasion.
