Anyone else feel like uncooked sphegetti?

Follow the ogy. People throw you around, you hit the walls hard, nothing seems to stick. Developmentally, is there something wrong? Or can you actually just be cut out to be a loner? I used to have a bunch of friends who I was really close with, now they all have boyfriends and/or don't return my calls. At this point, its been over a year since I really talked to someone I would call a best friend. I talk to people, just with no strong or long lasting relationships. I'm smart, but I try not to rub it in. I'm not extremely fat, or extemely pretty. Kind of homely, but open to new things and ideas. People say nice things about me, but no one really knows me. I overheard people at a lunch table across from mine playing a game the other day. Someone said, if there was someone near that you wish you could know better, who would it be? Me. Although it was nice, it bothered me and got me thinking. Please help. Am I just unapproachable? Do I not get out enough?
