I honestly don't get why people seemingly are against telling people about bullying (even suggesting you fight them before it), in my experience, especially in later grades, the most effective way to deal with bullies is to get someone with real authority over to deal with it. Yeah I know, sometimes teachers suck, so sometimes you have to go over their head to the principal which will do something about it, principals don't mess around.
Also, this might sound odd, but sometimes you just have to let the bullying build up so that they do something outside of verbally attacking you. If they give you bruise or break your stuff that is an undeniable proof of their abuse, and it will be dealt with.
