I am in this category, but have a completely different experience. For one I did not get tested until late in life (and discovered I had an IQ of ~150 according to the Mensa standard admissions test), and for another I was in private school all the way through high school. So I believe what made the difference for me was a combination of not growing up with that ultra-gifted stigma, attending a school with very small classes (sometimes I was the only student in a given class), and having a great deal of socialization with intelligent adults. I still had a lot of difficulty relating to others my age, and thus made few lasting friends. I also did my best to shy away from any attempt to classify me as a genius. I didn't feel like a genius (whatever that means), and didn't want to be considered one. This, in part, is why I didn't bother to get tested until into my 40s.
