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.
Breakup
A natural effect of the loss of a relationship that an individual had hoped to keep is grief, because the desire to keep relationships intact despite problems and complications is a natural human desire. This results in individuals undergoing a breakup displaying grief reactions that include symptoms like sleeplessness, depression, and thoughts about suicide. This tendency to express grief and depression is so prevalent that researchers point to it being a significant contributor to the first onset of major depressive disorder in young adults.
