Yes.
I have a gifted level IQ and performed very well academically, being consistently 2 grade levels ahead of my peers (4 grade levels ahead in maths).
However, when I graduated high school early I experienced a sudden stop. School was my obsession, my everything. I had no friends but the work gave me immense satisfaction. When that was gone I became unstable, felt very lonely, and lost my sense of purpose. As a young adult I have not been able to retain employment. Having Aspergers makes many part-time jobs an ill fit and I crave mental stimulation from my work. Not to mention I still cannot drive a car (and doubt whether I should because it is dangerous, I get distracted, and it is also very expensive).
So in answer to the topic question, yes I have been told all my life that I am smart. I don't doubt it. But my gift, so it seems, comes with a hefty price: the inability to function in even the simplest social functions. And as a result of issues with mental health, I have little to show for my mental merits.
