I use to be extremely shy in high school myself. Geeky, awkward, bullied to no end. The cliche. But then I went to college and... my dorm happened to be located in a Pittsburgh ghetto called Homewood.
So, I found myself in a situation where I HAD to break out of my shell. I learned to just... stop caring... about everything.
Now, I LIKE broadcasting my weirdness. I make my own ultra geeky hats and t-shirts and smile when people uncomfortably turn their gaze away.
Every time I make someone uncomfortable or break the monotony of their boring little lives I get some small crumb of revenge against the norm for the hell my weirdness put me through back in the days when I cared about what people thought of me.
Bitter? Angry? Cynical? Hell yes. To be anything else seems ludicrous to me at this point.
