I had similar issues way back in elementary school; but I took a different route. Instead, I dumbed myself down and worked on my social image so I wouldn't get picked on as much... Yeah, it didn't work out as well as I thought.
A few times, I had my teachers think I was autistic, or even the other kind of "Special" (usually also because my mind wandered throughout classes since I can learn without even paying attention at the main subject; completely splitting my attention). As for social situations, I had 2 reasons. First, I wanted to knock attention away from my voice for once in that time (primary target for bullies of various sorts), and make them instead mock me for being smarter than them. I knew how to operate a gorram computer exceedingly better than the teachers for crying out loud in 2nd-5th grade in the library. I even opened programs that no other kids could gain access to, as if I were the elementary school hacker. I almost gained enough street smarts in time to be able to turn bribing my designated bully with lemon heads (the large kind), to making exchanges of certain things I found little value in (like the dime-a-dozen candy while it was easy pickings back then; although I did enjoy them too, a worthy sacrifice) to make him less of a jerkass towards the rest of the school. When I would've been able to do the big reveal, I would've completely outsmarted and dominated the school bully, as the weakest kid in the school (or so everyone thought). But of course, this is me as an adult reviewing and kicking myself in the past for not having the balls to finish my plan.
My second reason for also holding back on my effort in classes was to also stay within a curve. You know, not be the best, but not be too average. So to put it, I didn't want to appear to be an arrogant genius through book smarts alone; and despite how far more brilliant than the other kids I was, I didn't want to discourage them. In hindsight, I also knew better scores just means more work which could lead to something I don't need, or would even likely use. Anyway, I actually was your overall "after-school special"-grade good kid. Yeah, that gave me some serious setbacks. At least after being the class target for a good portion of my life for various reasons; after spending a good amount of time being home-schooled as well, I returned with a vengeance (learning all sorts of things, and taking advantage of traveling while learning at times to further other kinds of training). So to put it, I still considered my freakishness; but instead, found it as an advantage instead of a problem. I did all I could to expand on those eccentricities, and find ways to exploit them for any occasion, by any means. Reminder: Beware the Nice Ones.
With unrestricted education of being home-schooled, tied in with personal curiosity, traveling at moments, having part-time odd jobs, I was no longer the same person when I came back for high school. It's an even more serious case with college. I'm still surprised old friends I had since elementary school still recognize me.
Now looking back has made me sad. As much as I wish my social life were better, I feel fortunate it was crap, otherwise I wouldn't improved on myself. A star in the great black.
