Agree with above. Just keep doing what you are doing. Meanwhile, consider a part time job at a lively place where other young people work. Or volunteer. Both are excellent ways of meeting people who might not just be associated with college.
I commuted for all of my college career. I did not make one friend at college, but I had a very busy social life with friends from work. I worked at restaurants, clothing stores, as an after-school day care counselor, and lot of other jobs. You should cast a wide net.
