Therapy has helped my 2e DS16 with his anxiety. We got help when he was 11/12 and he is now seeing a different person now that he is in High School. The new therapist is someone who specializes in gifted teens, but the first therapist who had no particular experience in gifted kids was still very effective in helping DS. He taught him a number of self regulating techniques that he still uses to this day.

Good Luck.
