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.
GROW
GROW's literature includes the Twelve Stages of Decline, which indicate that emotional illness begins with self-centeredness, and the Twelve Steps of Personal Growth, a blend of AA's Twelve Steps and will-training methods from Recovery International. GROW members view recovery as an ongoing life process rather than an outcome and are expected to continue following the Steps after completing them in order to maintain their mental health.
