This study examines the mental functioning of a three-year-old child named Ç. through the use of projective tests (Rorschach and CAT). Ç. experiences significant anxiety and obsessions which make it difficult for him to be alone, adapt to daily life, and regulate his emotions. The aim of the research is, to identify the fundamental anxiety underlying the intertwined anxieties and obsessions as well as to determine the stage of psychological development from which this anxiety originates. The assessments reveal that Ç. tends to repress his aggressive impulses due to unconscious guilt about potentially harming his mother. The inhibition of aggressive impulses and difficulties in being alone hinder Ç.'s ability to develop an autonomous self. Additionally, the anxiety about losing the object (the mother), disruptions in object constancy, and the need for a containing function are other significant findings. Consequently, it is concluded that the obsessions, fundamentally rooted in early experiences, serve as a defense mechanism to protect the inner world.
