In cases of extreme childhood trauma associated with abuse and neglect, one's sense of self is seriously compromised. Attachment patterns, symptoms, defensive operations, and character formation will differ depending upon the level of interference and impingement. When repeated trauma occurs in early childhood, the dissociative response may become the first line of defense for the person to rely upon. In its most severe form, patients are diagnosed with Dissociative Identity Disorder (DID). This paper addresses the case of a woman diagnosed with DID. It describes the restoration of a cohesive sense of self from the eight parts of a dissociated and fragmented self in the course of therapy. The clinical case material presented is that of the child part of her, known as Lucy. Her treatment resulted in the integration of the “it's not me!” self to the patient's knowledge that “it was me, after all.”
