Setbacks can be triggered by memories of old fears, new fears and stresses, or even minor changes in your life that threaten your sense of security. There can be a surprisingly quick return of all the old patterns (for example, "all or nothing thinking"). The setback can be small and resolve itself quickly, or it can be a devastating, catastrophic event. People tend to withdraw from setbacks in fear and fall into the trap of trying to fight them. Many revert back to old patterns of avoidance and feelings of hopelessness. It can seem as if you are back where you started with no possibility of any forward movement. In other words, you feel despair, and you feel stuck.
