In this paper the author explores the clinical significance of the presence of a depressed internal object in a patient with marked obsessional features, dominating the patient's internal world and restricting relations in external life. After discussing important aspects of the contribution of Freud and later writers to the study of obsessional neurosis, the author provides clinical material that shows the patient's tormented relationship to a feared depressed object that was manifested in the transference. Developing her argument, the author suggests that if the analyst does not fully grasp the primitive anxieties of the underlying state of mind she can be prone to enter into an aggressive enactment with the patient's sadistic superego. This kind of enactment may arouse excitement and triumph in the patient, but actually confirms his doubts and fears about the capacity of his object to contain him.
