Reconstruindo sentidos na interface de histórias: uma discussão fenomenológico-existencial da constituição do sujeito borderline

This paper discusses a clinical case of a 40 years old woman, diagnosed as a borderline personality disorder, conforming to CID-10 (2003). The paper proposes, by a concrete clinical experience, to discuss the phenomenological and existential psychopathology. At first, it describes borderline disorder according to existential phenomenology. So, the authors discuss the conceptions about the relation between health and sickness in Gestalt-Therapy and Daseins-analysis, trying to understand the way of 'being-in-the-world' and the constitution of the psychopathological phenomenon in borderline patients from the perspective of the construction of his life story, that is unique. At the end, the authors detach the great challenge of existential-phenomenological psychotherapist: putting the patient's clinical picture in stand by 'a priori' and considering how she expresses herself and sees the world, giving up the mere disease classification itself.
