Okay... I'll be honest: I'm trying to keep a serious mind at this, but you awfully sound like either a troll or Twilight fan. Sorry if that's not the case, but those aren't really rare...
I'll assume the biting part was referring to being a vampire? (If not, could you please explain in more detail?)
If so...
Tip: Vampires don't live in another world. They go to school, have a job and are stuck in the rat race just like everyone else. No vampire school, no vampire secret society.
It sucks feeling like you don't belong in a group, but believe me as I say this from personal experience: there's only one way to deal with it and it's... to deal with it. It'll make you stronger in the end.
About wanting to bite... I'm no vampire and so can't say "I know how you feel." so I'll give you the obvious answer: self control. Practice your discipline and learn to maintain it. It's a tough road, but a good one and it'll help you in many occasions. How you practice doesn't matter, just do it. Meditation, mental discipline exercises, breaking habits, etc. Hell, test yourself by taking cold showers if it'll help. Or check the vampire section (The Blood Track), I'm sure all that's been thoroughly discussed there.
(Same with being a werewolf if the biting part was referring to that instead.)
And this isn't a suggestion; it should go in the Mayday! Mayday! section.
