Susan Anderson (psychotherapist)
While Kübler-Ross, Anderson, and others have attempted to define discrete stages of grief, such as an initial period of numbness leading to depression and finally to reorganization and recovery, most modern grief specialists recognize the variations and fluidity of grief experiences, that differ considerably in intensity and length among cultural groups and from person to person. No grief stage theory has been able to account for how people cope with loss, why they experience varying degrees and types of distress at different times, and how or when they adjust to a life without their loved one over time.
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.
