Can i get a law for harassment put against her?

Well im 16 and this girl we used to be friends then the dude she liked is now with me i mean this girl is getting on my last nerves i got suspended because of her i cursed her out and said to leave my name out her mouth and for her to leave me alone but i got like 25 texts from her yesterday shes messing with me and my boyfriends life almost like stalking it seem like she doesn't have her own that's why she worries about me im tired of all this i deleted her from facebook and i blocked her but she makes fake profiles just to say stuff to me can i get something against her to leave me alone?
