The therapist I found is hopeless

Diagnosis psych was great. Referred me to 'an ADHD specialist' to help with next steps. This therapist has no idea about ADHD, keeps trying to analyze my childhood, and dismisses my diagnosis as 'a label.'

I thought getting the diagnosis was the hard part. Finding the right support is harder.

How did you find a good therapist after diagnosis? Red flags to watch for?
