The Missing Feeling Technique is a method to help identify and strengthen feelings that have been blocked. It involves identifying the missing feeling, practicing expressing that feeling through daily exercises for 5 days with a partner, and continuing exercises to rewire brain circuits that previously blocked the feeling. Examples of exercises include labeling feelings, practicing facial expressions of emotion, and using a "Hostility Buddy" to help strengthen controlled expressions of anger. The goal is to unlock emotional fluidity and the natural flow of feelings.
