Mos, the 5 stages of grief all in 3 pages:
Denial — One of the first reactions is Denial, wherein the survivor imagines a false, preferable reality.
Anger — When the individual recognizes that denial cannot continue, it becomes frustrated, especially at proximate individuals. Certain psychological responses of a person undergoing this phase would be: "Why me? It's not fair!"; "How can this happen to me?"; '"Who is to blame?"
Bargaining — The third stage involves the hope that the individual can avoid a cause of grief. Usually, the negotiation for an extended life is made with a higher power in exchange for a reformed lifestyle. Other times, they will use anything valuable against another human agency to extend or prolong the life. People facing less serious trauma can bargain or seek compromise.
Depression — "I'm so sad, why bother with anything?"; "I'm going to die soon so what's the point?"; "I miss my loved one, why go on?"
During the fourth stage, the individual becomes saddened by the certainty of death. In this state, the individual may become silent, refuse visitors and spend much of the time mournful and sullen.
Acceptance — "It's going to be okay."; "I can't fight it, I may as well prepare for it."
In this last stage, individuals embrace TCAS and the management which typically comes with a calm, retrospective view for the individual, and a stable condition of emotions.
Works quite well really!
