I wouldn't say I was a loner. But I was one of those awkward kids. My high school days are more or less one big blur to me because I spent everyday the same. It was like I poker faced through the entire four years. I can say I regret it. So I encourage you to take the first step. Sadly, its usually you that will have to take the first step. It'll be weird but so worth it to find the special few that will walk side by side with you through probably the hardest years of your life. Sometimes all it takes is stopping to help someone pick up some fallen papers, saying hello and telling them your name and learning theres. I know because that's how I met one of my old friends in middle school. Though she moved before our freshman year in high school. The memories of her being there...its helped a lot.

Good Luck.
