I think she is wrong in that you clearly have an Axis I dx. I remember your posts from last year. I remember how you were sent home from Europe. People with a "sensitive personality" do not get sent home from Europe.

As for ADD - if you do not have ADD, how does that reconcile with that you do not perform above average on the exams? You are clearly way smarter than average, and yet you perform below average on exams, so something must be at play. How a low level BPD or a sensitive personality can make a person consistently perform below her ability on exams is beyond my understanding, but that ADD can cause it is easily possible.

The T is not making sense and is contradicting herself - if she thinks that you have a sensitive personality, whatever that means exactly in her mind, then she should not be delivering such news (or, to be more precise, her hypotheses masquerading as diagnoses) to you in the way she does.
