Borderline Personality Disorder
The PDM (psychodynamic diagnostic manual) defines Borderline Personality Disorder as "Persons that tend to have recurrent relational difficulties, an incapacity for emotional intimacy, problems with work, periods of marked depression and anxiety and vulnerability to substance abuse and other addictive behaviours... They are also at greater risk for self harm... and destructive activities".
"The most commonly noted defences are 'splitting and projective identification'. Splitting is the tendency to see self and others in moralized, all-good and all-bad categories; i.e., in unrealistically positive ways or in unrealistically negative ways, or in both, in oscillating fashion. Projective identification involves failing to recognize troubling aspects of one's own personality."
