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
Many of the above examples of bereavement happen abruptly, but there are also cases of being gradually bereft of something or someone. For example, the gradual loss of a loved one by Alzheimer's produces a “gradual grief.”
