My father was a physician, and over the years I've become a real advocate for truth and fact in medical/mental health records...one's treatment depends on accuracy. If I were you, I would ask your T to explain to you why she feels your situation merits the diagnosis she's given. In my own case with PTSD, I minimized the affect the situation actually had on me. It wasn't until a year or so later that I understood that what I originally thought was a minor confrontation was actually quite life altering. One thing I learned from my situation was that it isn't whether or not someone else has it worse than you do, but what happens to people affects them "differently." You might want to give yourself a little time to assess what your T tells you and concentrate on how you feel about what happened to you.
