Some hours after a psychological examination that showed no disquieting signs, a teenager who had been placed in a group home tried to commit suicide with her boyfriend. After this passage to the suicidal act, we wanted to rethink this case in the light of works linking suicidal vulnerability and depression. Having hoped to find in the protocols of the projective tests (Rorschach, TAT), clinical signs of the acting out, we noticed instead an inclination toward the bleaching of affects and feelings, just as had appeared during the gathering of anamnesic data and experienced within the clinical relation. A finer reading of protocols reveals under the appearance of a white depression a vulnerability which required individual psychotherapy.
