hating it

I think the worst feeling of my whole experience at school is lonliness. In a sea of 4000 people, I feel like I have no one but God, not that I necessarily need anyone besides God, but a friend would be nice. Not just any friend, a really sincere friend that really cared about me. I almost cried today telling my dad about how I had no one to go to lunch with and that I was eating subway by myself, the casheir even recognized that I ate there so much and gave me a rewards card. Seriously...I hate this. I am tired of the superficialness of college friends, maybe that's why I continue to have no close relationships, or even many surface friendships, because I see no value. What on earth do I do? I don't want to invest my time in things I'm not interested in, or when I have other priorities to fill, but I want a friend.
