Internal Family Systems
Parts are subpersonalities that may be experienced as thoughts, feelings, sensations, images, words, sounds, inner voice, and even physical symptoms. All parts want something positive for the individual and will use a variety of strategies to protect Self.
Managers and Firefighters protect the Parts that have been sent into exile. Managers run day-to-day life to keep everything running smoothly. Firefighters are impulsive, frantic, reactive and often destructive. These are the parts that distract us or dissociate us until the perceived crisis has passed.
