Leave me Alone

I am 13 years old. This is my story.
I met this girl at school I have been in her classes a few times during my life. When I was younger she stole my stuff and pretended to be my friend.
I had enough of her so I didn’t talk to her during year 5 and 6.
Then year 7 came.
I was put in her class. I tryed to be nice to her. It was going ok till she ask to hang out with me and my friend. We said ok. I told my friend to to trust her on everything.
Then she asked my friend if she could go over to her house. So them to together. I was fine.
Until she came to school on monday telling the guy I liked I liked him. which means my friend told her. I got angry. But in the end I forgave my friend but not her.
Now for weeks and weeks she keeps calling me these names with her new friend.
Then one day she said I was a mistake.
This is really upsetting me and I hate walking past her and she yelling out something about me in front of everyone.
I just wish she could leave me alone. I am scared, I’m not one that likes telling teachers though I will share my story
