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.
Grief (novel)
Frank - Frank is a sarcastic yet insightful friend of the narrator. He seeks to help the narrator overcome his grief and move on with his life. While the narrator argues that grief maintains a dead person's “presence on earth” (18), Frank argues that regardless of whether or not you grieve for the deceased, they are gone and there is no bringing them back. He helps the narrator interpret the actions of his landlord and also assists him in understanding the narrator's own emotions, his relationship with his mother, his need to be needed, even his relationship with his landlord's dog. Towards the end of the novel, it is revealed that Frank has cancer, and that his days are numbered.
