The borderline personality.
These individuals, who are often bright and verbal, present with intriguing physical and emotional symptoms. The pathology of the borderline personality begins at an early age with a failure to integrate a sense of self. Patients with this disorder have little sense of who they are or what they are feeling; anger is the one emotion felt consistently. Such patients may present with psychosomatic symptoms, brief psychotic episodes, depression or suicide attempts. Extended psychotherapy is generally required for enduring benefits.
