Anticipatory grief
The five stages namely, denial, anger, bargaining, depression, and acceptance proposed by Elisabeth Kübler-Ross in her model of grief describe the process by which people undergo after a loss. Anxiety, dread, guilt, helplessness, hopelessness, and feelings of being overwhelmed are also common. However, it is important to note that anticipatory grief is not simply normal grief begun earlier.
A Grief Observed
"A Grief Observed" explores the processes undergone by the human brain and mind over the course of grieving. The book questions the nature of grief and whether or not returning to normality afterward is even possible within the realm of human existence on earth. Based on a personal journal that he kept, Lewis refers to his wife as "H" throughout the series of reflections, and he reveals that she had died from cancer only three years after their marriage.
