This is the situation in my opinion, the differentiating factor in diagnosing the difference between acute stress disorder and PTSD is time.
To diagnose acute stress disorder, the disturbance lasts for a minimum of
2 days and a maximum of
4 weeks and occurs within
4 weeks of the traumatic event.
What this means is that after the condition has lasted for more than 4 weeks, the diagnosis of Acute Stress Disorder must be changed to something that is more appropriate based upon the symptoms (more than likely PTSD). What the Air Force did was illegally (by today's standards) diagnose you with personality disorder and discharge you for a condition not a disability.
I think that the AFBCMR is still robbing service members economically by recharacterizing the discharge as secretarial authority. This leaves them off the hook from paying a medical retirement and makes them only liable for severance pay.
I would fight this in Federal Court and request that the discharge be upgraded to medical retirement, and request the back pay. If the condition is combat related, I would also request CRSC to be retroactively paid.
Personality disorder was misused frequently by the military to remove service members off the book. It was such an issue that in early 2014 DoD instruction was given to basically "knock it off" and get a proper diagnosis of any behavioral health conditions.
