See, I would have kept the red eyes, even with contacts or glasses, and just ran with it. "You callin' me a Demon? Yeah, I am fucking demon." Martial arts and weapons clasess would have been, and still are, a must. Information like "Human flesh, when cooked, tastes like pork" is useful, especially if you make them think you know that first-hand, and not just from a book. Other then that, if you can't take it, get different colored contacts, and dye your hair. If you can, then good-on-ya'.
That's about it. High-school will be done soon, and when you get to College, all that shit ends (unless you go to a cruddy college). I mean, just today, my dorm-mates and I ran around our dorm shooting people with Nerf guns yelling "John Luc (Luke) has infected the dorm!" Also, we have an open furry on campus, who walks around with clothes that say "Furry," and he wears a collar. No-one cares. That's just what he's like.
