In this study, the Rorschach and the Thematic Apperception Tests are used to analyze the separation-individuation process in the case study of a twenty years old male patient, struggling with object loss. The aim is to examine the impact of object loss and to address its place in borderline pathology. The boundaries that are ambiguous at the adolescence, becomes more distinct during the period of becoming an adult. However, as in this case this is not always easy. The inadequacy of motherhood function makes it difficult to become an adult, to cope with loss and to set distinct boundaries. The Rorschach Test is used to explore object loss and its connection with maternal image, as well as with identity, sensitivity towards absence, narcissistic vulnerability; difficulties concerning separation and depressive affect. These issues are evaluated respectively by the cards of (I,III,VII,VIII,IX); (I,V,VI); (I); (I,X) and the color responses Depending upon separation-individuation axis, the object relations are evaluated by the TAT. The narcissistic inadequacy, the separation issue, the depressive affect, the vulnerability towards loss and the internal/external boundaries are respectively examined by the cards of (1); (2,13BM); (3BM) and (12BG,16,19). These different features are examined through examples from the projective tests based on the French school method. Finally, it is discussed that whether certain borderline pathology features could be viewed as an extension of adolescence characteristics.
