The paper describes an analysis with a very difficult, emotionally inaccessible patient who, after more than a year, unexpectedly terminated the analysis, leaving the analyst with a sense of frustration due to incomplete and interrupted analysis. In the theoretical section of the paper, the author presents his understanding of the creation of such a pathological organization, starting with Freud’s concept of death drive, then going on to Melanie Klein’s and her successor’s discoveries. John Steiner’s concept of ‘psychic retreat’ helps us to understand the process of development of a pathological organization of personality. In the last part, the author describes how he works through mourning and prompts reflection on the reasons for the premature termination of the treatment by the patient. He indicates the causes in both the patient and the analyst.
