I quit facebook for many reasons but one was that it was way too depressing seeing all my "friends" doing so many things with their life while I did nothing. I say "friends" in quotes because these were people I used to hang out with but eventually they stopped responding to me and didn't initiate any communication with me.
I have one friend, but we're so opposite in some quite important areas of life that I don't know if we should be friends or not, but if I don't keep him as a friend then I have none. And I don't know where I would go to even attempt to make new friends. But, like you said, I also sometimes wonder if I really want friends or not, I'm not sure if I'm a good enough friend to have friends. And I have trust issues, all of the friends I've ever had have either ditched me or betrayed me at some point.
I hope the best for you with college and everything, I think you're a cool person.
