All mental health issues arise from confusing external and internal objects (examples: psychosis, narcissism).
I suggest that there is a single clinical entity Personality Disorder with overlays (narcissistic, antisocial, borderline, histrionic).
Each overlay has 3 states: overt, collapsed, covert.
Transition between the states and the overlays is a reaction to gaps (reality intrusion or failure) and to narcissistic mortification.
