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
PGD is defined by its symptoms, duration and intensity. The symptoms are intense yearning for the person, identity confusion, difficulty accepting the loss, bitterness, emotional numbness, inability to trust others and the feeling of being trapped in grief. These are present every day, causing significant distress and functional impairment, and remaining intense, frequent, and disabling for six months or more after the death.
