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.
Mourning
The above five phases can be linear but often a mourner can flip back before starting to move forward. A good way to pass through grief is to understand what has happened and share the feelings and emotions with relatives or people who also are grieving. These steps do not necessarily follow each other. It is not an inevitable process.
