Anybody who says you're worthless is lying. I've never yet met a person who was worthless, and I really doubt you'd break that pattern. So what if you're nerdy and you need glasses? How does that make you any worse than people who were born with good vision and a talent for social skills? They didn't work for those things... whereas you, most likely, have been working your butt off to get your social skills at least halfway up to par.
Frankly, I'm sick and tired of the way people tell perfectly good crazy folks that they're not worth anything. Yeah, I'm crazy, and I'm proud of it, and if they don't like it they can go take a hike, y'know?
BTW--I wear glasses, too (and 20/200-something). Suggest you go & find yourself a nice stylish set of frames--they can really add to your look.

Oh, and make them do the high-refraction-index plastic lenses; you don't want thick lenses 'cause they'll just make your eyes look funny.
