Hi The Fox & the Hound, probably best that you haven't heard from her. It doesn't sound like she's been much of a friend to you, so maybe best to go your own way without her do you think?
As for the bullying though, you have to tell a teacher/tutor. There's no reason at all you should have to put up with bullying!!!
And as for hating you, they probably don't even really know you, right? They are probably a lot more upset/annoyed at/frustrated by/resentful towards.............something about their lives, their experiences, themselves than they are at you. It's their failing they're behaving that way, not yours. And please don't let them get away with bullying you, please tell a teacher/tutor.
