Long, but I don't feel like I fit in (college freshman, second sem.)?

Well, its second semester and I don't have any real friends. Not even friends. Like, these are just people that I choose to talk or not to talk to. I feel alone, and it doesn't really help when 1)I don't like talking to people because they run out of things to say and they just do stupid things and I don't have the patience, and 2)I don't know which extracurriculars to do. I was recently interested in a position in my college's singing group, and they pretty much threw me into that, and I didn't feel like I was interested at all. But every other freshman seems to be having the time of their life at college, partying with friends, actually sure about their major (and I'm in business but as of now I have no idea WHY other than my dad's final share of money determines if I even go to school here and he's ordering that I major in business. I haven't found the confidence to speak up to him yet, he's very strict and gets angry when things don't go his way), they have a hobby they KNOW they love and are excelling in- and here I am, doing-nothing-but-getting-good-grades high school alumni, second semester freshman, barely getting past with a 3.3 as a 1st gpa, and instead of talking with others would rather write about her life in journals and Yahoo almost everyday. I don't feel like I fit in, I still feel like I'm a wierdo in high school- the only difference is I can do my homework whenever I feel like it and everyone is nice to everybody. ....If there were something on campus where people LIVE to hear about other people's lives on paper and/or through acting, I would be thrilled. Essentially, I don't feel like I fit in. What should I do if I don't even like talking to people? What extracurriculars (or majors possibly) would you recommend just by reading this? I want to be popular and a famous positive influence celebrity/figure someday in whatever I do, but I know I need to start soon (and I feel behind compared to others), and I don't like being told what to do/controlled (from living with my dad). Any other advice?
