My small town school had instances of missing teeth, broken jaws, one kid beaten far enough to require hospitalization for 2 weeks, etc. 10 years later, the popular kids say that there was no bullying and it was all intended in good fun. My therapist didn't even believe me at first when I discussed the things that were going on at my school, but luckily I do have some reminders of those times on visible places.
Your school sounds awful, I'm sorry. I went to a pretty diverse school with >2000 students, so there was some violence, but it was either mutual or gang-related. Petty teenager dickishness existed, but nothing like the kind of Stephen King bullies you describe. As far as I know, at least.
I admit I could've been oblivious, but for that to be possible already indicates a friendlier environment than these descriptions.
