Back in my youth bullying was still every bit as much an issue. Some thing never really change.
I wasn't bothered, but then I was known to be part of the 'army types' and we were known to have plenty of legally owned weapons, not pistols, but rifles. This is long before any of the crap that is normal in schools today though.
My son though has trouble with bullying issues occasionally. Your best defense, is to repeatedly report the offenders, never let up, generate a nasty file folder of complaints, make the problems out to be genuine problems, be willing to not accept it. Eventually staff WILL 'discuss' it with the offenders and that's how it's done. Find out all the other people that are being hassled, drag them to the office and make them log complaints too. Make it apparent it isn't just you complaining. My son saw to it that one problem was told knock it off or he lost his year. Try imagining doing a grade all over again. Yeah even bullies don't want to throw away a year.
Fighting solves nothing. Doing nothing of course solves nothing. And saying that reporting them is being a wimp (or use whatever label suits you) is no good is coping out.
If you don't want to confront the bullying at the official paperwork level, then get used to being bullied.
