Tough spot. I am a commuter student in college and can relate with you a little bit. Basically you have to be really proactive about going out. Try to find something to do every night even if its just going to the gym or going out by yourself.
You want to get a lot of exposure so you have to go out a lot in order to build up your options. Say hi to a lot of people and keep in mind that it is better to seem disinterested at the same time.
Also, lower your standards. Great article on that->(

Seriously, sometimes you have to start off talking to the lowest, ugliest, and fattest then work your way up. I always feel better about my game when I do that and there is plenty of ugly people that need friends. It's ok to start there. If all you need is friends to go out with then do that.
