I am pretty sure asking for a diagnosis here is not a super fantastic idea, cause mostly we just play psychologists on 'tv'...that said, if I were you I'd start by reading up on giftedness, posting more details here, people might have ideas for you. (I imagine the 'diagnose me' request was somewhat tongue-in-cheek).
What sorts of things do you like to do? How are you employed, happy with job? etc...that sort of stuff. You probably already know a lot of these second exceptionalities can sound a lot alike. Finding the right sort of dr to consult with might be key if you feel the issue is keeping you from really doing what you want with your life. Best of luck, welcome! smile
