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.
Prolonged grief disorder
Grief is a normal response to bereavement. Researchers have found that 10–20% of people experience a prolonged response to bereavement that impacts functioning and has adverse long-term effects on health.
