I can say without a shadow of a doubt that it's been the biggest barrier between me and a happy life, simply because my parents began to over-estimate me - naturally seeing as they thought they had a genius on their hands.
I'm in almost the exact same situation - I'm sure I didn't score as well as you probably did, and I'm a college dropout (hopefully I'll be dropping back in next semester or so), but I know how suffocating "potential" can be.
But I know I have a pretty high IQ, too. And that's been a source of some comfort, I guess. I mean, a high IQ is only moderately useful. There's other kinds of mental ability that are much more useful, like cleverness, or a good memory, or determination. High IQ people don't seem to come to any less wrong conclusions than anyone else, many times - they just come to those conclusions much more quickly.
For me it's just been a thing where I've discovered my limitations, probably much later than most people do - in fact that high IQ might have retarded my progress in finding my limits - and now I'm coming to understand the way in which, as I once saw it put somewhere, "I make myself my enemy."
