Help? Teasing Prob?

Me Ex- B/f'z Ex G/f (still friends) She Keeps Teasing Me, To The Point I Wanna Cry. Like Today I Was Walking, She And Her Friends Start Pointing At Me And Saying "Ewww! It The "It"! Eww! It Would Be Better If U Werent Here! Eww Im Going Blind!" I Basically Try To Ignore It.....But I Cried As Soon As I Got To The Bathroom.

So My Mom Ish Gonna Bring Stuff.......So The Girl Cant Mess With Me Then.....But When Me Mom Leaves Im Freaked Shes Gonna Do It, And I Cant Stand It! HELP!
