I am not a people person either and do not care to make friends with people. BUT you need to be respectful of people and not be so blunt, go with the flow a little but that does not mean you need to go really out of your way to be nice to them.
You need to be at least semi-sociable with people. A college degree is not a guranteed job anymore. I have a college degree and several certifications and it took me about 5 months to get a job and that was with the help of a professor I was close too. Now I have been working a while and everything is great :D
