To me that seems too simplified....for instance people with paranoia issues can have diminished self confidence as well, its not always 'delusions of granduer'. My hyperviglence has not mellowed out since being away from the situation that caused my PTSD, if anything its only gradually gotten worse. Also I can see how hypervigelance could contribute to paranoia or at least some paranoid thoughts(due to the brain trying to make sense of the hypervigalent feeling) for some people. Also people with paranoia can be concious they have issues with paranoia and may sometimes be able to identify when they might be experiencing paranoia rather than a real danger or people really out to get them....people with issues like that are not constantly in a psychotic state you know.

Also paranoia isn't a mental illness in itself, it can be a symptom of mental illnesses but by its-self its not considered a mental illness.

Also illness, injury....whats it matter either way it effects me just as bad. Could be said plenty of other mental illnesses are more mental injuries as well, like depression since external factors heavily contibute, also though PTSD has genetic/enivoronmental factors aside from the trauma itself as well....hence why two people could experience the same trauma and only one might develop PTSD.
