My last therapist told me after our first session that I don't have AvPD, even though I was professionally diagnosed with AvPD no less than three times.

I feel like in the end, she did more harm than good because she didn't take into account the AvPD and didn't realize just how deep certain issues went. (Maybe it was partly my fault as well because I was not 100% open/honest with her but if she hasn't branded me as "only" socially anxious, she might've picked up on that.)
