The goal of this article is to illustrate psychoanalytical concepts of subjective appropriation, symbolization, primary guilt and psychotherapeutic interplay. Those concepts found their support from authors such as Freud, Winnicott and Roussillon. First, I will present a briefly review those concepts and then illustrate them with a clinical case. The patient has been in psychotherapy with the author in a psychiatry outpatient clinic. Modifications have been made to preserve the anonymity of the patient.
