Most Helpful Guy
"the only people i feel any kind of friendship with is the people i work with in my department, my roomate, and my brother who also lives here as well."
I'd focus energy on the few people you have around you. It sounds to me like the way for you to get to know people is through organic means and overtime.
Most people don't click the first time (friendships or relationships) but rather over time. Keep trying to network through the means of your friends now and eventually you're social circle will grow. Be proactive about trying new things you think you will enjoy and eventually you'll bump into people of the same interest. If not? you had fun doing something you like.
for me? I love being active, i play tennis and do crossfit and in doing so... i've developed a friendship with many with my same interest. I now go out and do other things outside the gym with them. So this worked for me.
