I used to years ago when I was at school. Typical stuff, the worst I can remember was if I was passing certain people in the corridor, they would grab the side of my head and kind of smash it into the wall. It svcks, but chances are you'll look back on it and realise it's not a big deal.
It's nice for me as I live pretty much in the same area, and all the kids who bullied me are either unemployed and tied down with loads of kids they don't seem too bothered about, in prison, or serving me in some capacity - one of them cashed up my petrol the other day.
Just hang in there, and stick with good friends and you can't go wrong.
I should also add that one woman who used to bully me actually came over to me once and apologised for the way she had treated me back then. Some people are just [censored]s, and nothing will change, but some are just immature and too stupid to realise how hurtful and cruel they're being right now.
