I'm 23 and in my first few years of college I had those types of friends even though they did not match my personality at all looking back on it. Trust me you're not lame, I WISH I would've chose to do my own think instead of hanging with them all of the time just to try to be more out going, drinking, smoking, and stuff..it just wasn't me and I forced myself to be something I was not and I ended up friendless at the end of it all. They like totally stabbed me in the back once I started to become my own person and side against talking behind everyone's back. I just didn't get it then to go smile in their face and call themselves their friend? Ugh. I decided to mve out and they bleached my couch! It was crazy! lol

I completely understand where you're coming from "clawing for friends". Well if you don't want to feel like a ----- you could just go out and say hi and introduce yourself then just say that you just came out to say hi but you have to study. If they can't understand that then you really don't want to surround yourself with that. I learned the hard way. I transferred schools and join an organization (not like a sorority or anything like that) on campus and found sooo many people with personalities like my own..I was shocked, plus they are study hard people and keep me on track with my studies as well. We have so much fun and it's pure simple fun even if it's us just being random. Lastly, believe it or not I actually found my two best close friends over craigslist and my boyfriend as lame as that sounds lol but I've never been happier with the people in my life right not. So, you can be outgoing, but do it with the right crowd for you. I hope this is helpful :/
