Returning to the Internal Family System model it is important to recall how parts/disowned selves/roles, their development is always specific to an individual’s temperament and interpretation of their personal experience.
For example, exile parts digest negative messages which began to form in our earliest thoughts about ourselves and the world around us. These wounds or burdens then form parts of our core personalities.
We are not always aware of these core aspects. This lack of awareness can cause major problems for us when the formation of these “first” parts becomes isolated from the rest of the internal system.
