Yeah, unless the laws/rules are different between our countries, she can't technically give you an official diagnosis. You need a Pdoc or psychologist to diagnose you. Mine T has a masters too and while he's said "I think you have X", it's not official unless my Pdoc gives the diagnosis to me. That said, having a good T/Pdoc relationship can help your Pdoc to better diagnose you.

I would be wary of reading too much into this. I'd definitely question your T about what they are talking about. In regards to being smart enough to read a book, I'd honestly say, "Uh....should I take that as a compliment..?"
