My fake friend

Hi my name is Deborah and I had a fake friend. I knew this girl since second grade we have been childhood friends. And then once I started 6th grade I was happy. But that once changed in 7th grade she had these two friends that I didnt like It was a girl and a guy. Her guy friend would always talk about me and would always be fake and rude to me. I told my friends and family but no one believed me except my two friends. I had a new friend her name was Ann and I could already tell he didnt like her. And the girl I dont like she to me seems like a follower when I was at my algebra class my childhood friend told her to hit my head and she did just that. My childhood friend she just started to not be nice to me and I thought I was the only one there were many other like me and they were being fake to My childhood friend and her other two friends. And know I dont know if I should tell the councilor or just ignore them.
