As I recall, you have expressed concern that you have not been to a psychologist who deals with the gifted.
This is really worth traveling for, if needed.
I would hate to see your child continue to be diagnosed with Disruptive Behavior Disorder and Mood Disorder NOS if this is a kid who has issues with overexcitablities, sensory issues, or frustration with boredom.
If he is 2e (gifted and does indeed have a behavior disorder or something else) then I would also want him to be seeing someone who can understand the interplay between those two.
