I cant seem to succeed outside of school?

I'm a college sophomore and I do well in school, 3.93 well, but I've come to the realization that school is the only thing I'm good at. In my life I haven't been particularly successful at work, with girls, I can't drive, athletically I'm an abomination, and even my family doesn't give me much respect, let alone a real chance to prove myself. I feel terrible and Its to the point that I question my own worth as a human being. I don't understand. No matter what I do, how hard I try, I just can't seem to break through in these other parts of my life, to achieve even a marginal amount of competency. I feel like such a loser right now. What do I do? Should I consider just resigning myself to a career as an academic or do something like join the military? What do I do?
