Using one extensive clinical case report, disguised for confidentiality, the paper describes and demonstrates the three areas of potential progress and therapeutic change using Kleinian psychoanalytic therapy. The terms naming, claiming, and taming are used as shorthand to explore the manner in which containment and interpretation can lead to the patient gaining new psychological awareness, facing previously unknown or unbearable thoughts and feelings, and gradually managing and resolving those internal conflicts and relational struggles. Loss is often a primary element in treatment problems which the case report highlights.
