By looking only for jobs that can be done by a single person working alone, you'll be (1) making it much harder to find a job (not too many places would be interested in hiring someone right out of school as the lead developer on a project) and (2) depriving yourself of the valuable experience that comes from working with people who are more experienced in your field.
One last point: the tech world is full of people who were the "odd man out" growing up - that would be a pretty good description of me and a lot of my co-workers. Actually, I'm still pretty much the "odd man out" in middle age, but that hasn't stopped me from having a successful software development career working with (and even managing) other people.
Best of luck in whatever path you choose to pursue!
Fortunately social skills and physical fitness can learned and practiced. Suggest reading Dale Carnegie's classic on handling people> http://www.goodreads.com/book/show/4865.How_to_Win_Friends_a...
No matter what you're doing, advancement often means managing others, helping others with their jobs, organizing teams, talking to clients, etc.
The good news is, it's not too late. Some people seem to be born with awesome social skills, others have to learn them; but they are learn-able. I would consider social skills as important as any other technical skill you're learning in school; they will be just as important in the long run.
Oh since you are in school I'll assume you are early 20's. The above advice becomes more true as you get older.
