Bullied by my “friends”

For most of my primary school life I have been bullied by my fake friends. Sometimes me and these two girls are best friends but they arent actually. They:
– Use me
-make fun of me
– call me horrible names
– start rumours about me
And much more

I have talked to many adults about it including my head teacher/ principal yet it still hasn’t stopped and I don’t know what to do.
I usually feel isolated, alone and sad so if you know anyone that is getting bullied tell and adult but don’t interfere yourself but let that bully victim know that they are not alone and welcome them to hang out with you. That is all you need to do. Please raise awareness for bullying because it is a terrible thing and it makes people feel and unimaginable pain and they might start to hate themselves! Please raise awarness and STOP BULLYING!
