I have never been bullied, but I did experience the usual stuff that I think most teenagers or children experience, and when you are going through such a hormonal and stressful time, it really does not help to have those there whose only intention is to take out whatever bull is going on in their own lives on you. You have to be firm in your boundaries, and let people know that you are NOT that girl that everybody can just dump their insecurities and fears out on.
I was always taught that if someone hit me, to hit them back. Screw going to the teacher, and I tried to go to the teacher once, but teacher's are human too and just want you to shut up so that they can get through the lesson most of the time, and so they will shush you and nothing ever gets done about you being hit or called names. You really have to take matters into your own hands, at least I did. I never had to in my teenage life though, and by the time I was a teen, everybody knew their place as far as I was concerned lol.
