I've recently read Wave written by Sonali Deraniyagala. It is a memoir of a woman who was left alone after losing her two little sons, husband, and parents in Tsunami caused by Sumatra Earthquake. She is a researcher from Sri Lanka. It was somewhat distressing to read. However, at the same time, it was such an excellent piece of work that describes a tragic experience of loss with amazing exquisiteness and unrivaled accuracy.
Belief that she is not allowed to have any hope
Regret and self-condemnation
Resentment and remorse
Avoidance and yearning
Detailed memories that suddenly revive and intense emotion and thoughts that follow
Friction between people around her
Relationships with people supporting her
Agony and pleasure in approaching familiar places or sceneries, except that the pleasure only appears after quite a long period of time
I learned that she was advised in a therapy to put all of those emotions in her own words, which was eventually published as her memoir after eight years.
Althogh it may sound like an ordinary analysis, I feel that she reveals with all her senses how the experience of "loss" transforms in the passage of time. Within herself, her lost sons grow up, see things, speak out, or deepen their thoughts.
