Quick note after reading some of the other comments: Therapy isn't for everyone, and when it's bad, it can derail your life. Be careful going into a therapeutic relationship when you're feeling vulnerable (I know, that's when everyone goes, but still...). Don't let anyone "diagnose" you with anything prematurely. If you're high IQ or have "excitabilities" or whatever, some of the things that are well within the normal range for you can be pathologized as bone fide mental illnesses by people who either don't know any better or are a bit too eager to spot the potential for a long-term customer. Don't be afraid to switch or quit. (That should apply to anything important in life.)

Also, IQ may not define you, but if you're high on that scale, exercising it can make your life SOOOOO much better than it would be if you ignored it in favor of "more important things." (I don't think anyone was implying that that's what you should do, but if you're coming from a background of having your intelligence undervalued, it's totally on you to stop doing that to yourself. Very few others will understand that the IQ really DOES matter more for us than it would for most people, not just in a practical sense but for basic enjoyment and quality of life. It's like being an athlete with nowhere to run.)
