Well my dad doesn't really care and my mom is with her boyfriend and she doesn't think of me as her child anymore

Man that's a bad situation.
Others have mentioned the cops, that might be your only solution. And tell the principal you'll sue if he doesn't stop it.
I remember when I was young, in the 5th grade, there were some kids bullying me. The teacher was watching as they did it. I told them to stop and they didn't. So I got pissed and told that teacher I'm telling the principal you won't do anything about it. Man she followed me all the way down the hallway trying to get me not to say anything.
I can't remember what happened after that, but I remember it being a moment when I felt I was in control.
You are in control, so never feel as if you aren't. There are things you can do. I personally want to teach those girls a few lessons myself, but unfortunately this isn't a virtual reality forum. All I can do is type.
I wish you the best of luck though because you're a very beautiful girl and I have no doubt those girls are jealous.
Fighting back can be good if you are strong enough. If someone touches you, touch them back. Just know at that point the cops won't help you.
