Denial hides secrets from one's self. It's usually an end process of a sequence that begins with lies. Lies hide the secrets. Noted author John Bradshaw defines denial as "believing in spite of facts." It has a cousin called delusion. Delusion, Bradshaw says, is "sincere denial." Denial and delusion are maintained through silence. Such protects the person's option to keep doing what they are denying. It hides the self from being overwhelmed by guilt, shame, or despair. Discovering and overcoming all this in therapy is momentous progress towards recovery and wholeness.
