How Alone I Really Am

I've been thinking a lot lately.  I have come to realize how lonely I really am.  I go to Penn State University, the number 1 party school in the country, and yet I haven't gone to one party.  I've been going there for three semesters now, and I haven't made one good friend yet.  There are some aquaintances, people who I just say hi to, and that's just about it.  I live ar home, so  I don't have any roommates or anything.  A few of my good friends from high school have moved away, what I thought was my best friend doesn't contact me anymore.  Sometimes when I get so tired of just sitting at home and feeling lonely , I make up random excuses to go walk around campus or something.  Here's the thing, some people like being alone.  Well this isn't me, I want to make new friends, I want to go out and have fun, I want to find that special one to spend the rest of my life with.  I have the want and will to do these things, but fo some reason or another I can't let these feelings out.  I don't know if I need to go to therapy, which I think I probably do. I just don't know how to go about telling my parents without it being awkward or embarassing.
