Good psychologist. DD12 has seen a therapist who specializes in gifted kids for several years now and the experience has been positive for our whole family. She's a valuable ally at helping DD understand herself and DH and myself to understand her. We started because an injury in the family made her extremely anxious about her physical person. But the work they do has gone beyond that particular issue.

Being very smart means that in some ways you are very different than other people. You also have disconnects between your intellectual capacity and your life experience and emotional development that can cause issues. We talk a lot on this list about perfectionism, anxiety, sensitivity, loneliness, social disconnect, existential anxiety, etc. If you have a DC who is challenged by one or more of these issues, having outside help can be wonderful.

The general consensus is that you need a therapist who specializes in gifted populations because they present differently than neurotypical children. Sounds like your psychologist put you on the right track.
