MC...you said you just turned 13. Why do you even care?
As to your issues: contacts, so what, altiods or atomicfireballs, being a nerd is fine, and washcloth.
*shrugs* just be more self-confident. it'll get you all sorts of places.
As for me...17 and single by choice, rock on! Of course, I had to dress like a gangsta, quit wearing makeup, chop all my hair off (growing it back out though), and turn down a few offers along the way, but its extreamly liberating.
