I'm curious as to why you can't do anything about your problem for about a month. What do you mean by that?
Anyway, I found college to be isolating, too. There are so many slackers...and they're especially prevalent in lower-level classes. You'll definitely find more people like yourself when you start getting into classes that are more specific to your major. And as for your roommates, have you mentioned anything to your RA about them yet? If you don't trust your RA (there are lousy ones out there :( ), talk to another RA in your building. You might have to see about switching rooms, which isn't always something you can't do at the beginning of the school year considering that Housing and Residence is trying to sort who did and didn't arrive on campus, and that there's usually a bunch of people who'll drop out within the first month or two.
Does your college have a counseling center? If so, I definitely recommend that you take advantage of it. The university I went to limited the numbers of individual sessions you were alloted per year :x , but, nonetheless, it was still better than nothing. Also, there was group counseling, but you had to sign up for it early on because the dynamics of those groups did not permit people to join late.
And even though your studies are important, you probably should do a few extracurricular activities. They'll constructively give you break from homework and class, help take your mind off of your roommates, and you may come across some like-minded folks in these groups. Also, extracurricular activities are good thing to list on your resume. Employers like to look for people who did well in classes, but also took the effort to do other well-meaning things with their time.
