Am I Wrong About Dumping My Kinda Best Friend???

ok so heres the story, Theres this girl at my school named Linzy, she was one of my best friends until me and my other best friend Christina like dumped her.But you cant blame us though, shes just plain MEAN!!! If you accidentally say the wrong thing to her she’ll break you down. For example if you accidentally spell her name L-I-N-D-S-A-Y shell get so mad at you, she’ll rubb it in your face for life and publicly humiliate you,and she might even take your stuff, like your CELL PHONE and she’ll pretend she doesnt no where it is and then you finnally “find” it in like the bushes or something (trust me, I know, bc she did it to me, a lot) theres like never a limit for her, she’ll keep going until you cry,and then when she thinks that she might get in truoble she’ll be like,” omg, why do you take everything so seriously???” So I guess she thinks shes joking but her “jokes” DONT make you laugh, more like make you cry, and hurt like never before. So today she had left me a message on my phone like she meant it to be a prank call she obviously forgot I have caller id,lol, so neways she left me a message thats like kinda funny she was just making fun of my message you hear when you call and I dont answer, so neways I sent her a text that said, Whut do you have against my voicemail???, lol, like I was joking and shes all like denying it and then we got in a argument about how I ALWAYS blame HER and how I never liked her and she thinks I think im always right, ugh so I just had enough and im like ok im done good bye! and she like ok you can go cry now drama queen, and then I flipped and im all like “ you no whut linzy, shut the fudge up!! ( I wrote the real word) and then shes like ok luv ya too bye!!!, and thats when I texted Christina and shes like she did that to u??? and im like yea and then we agreed to both send her a text that sed, “linzy, I dont like you nemore and I dont want to be your friend nemore!”

So you think that I was too harsh? I mean she was/is nasty and mean… but did I go too far this time??? HELP
