<human>: Give me the gist of the text in a nutshell

I recently moved to a new school due to bullying in the one i went to last year.I have made many friends and i am getting along with a lot of people as well.The downside is one girl keeps harassing and insulting me,She does it on the low thinking i won't notice but i do have ears and i do have a brain.She recently started talking about me to my face so i ended up calling her a "Little putrid cunt" and all her friends kept bugging me until one of these people i call my friends told her.So now shes still saying rude remarks about me such as "Shes so big i really don't see how she fits in that chair!" and "Shes fat as shit i don't know how she can even fit her jacket on the back of her chair without covering completely.".I have never liked being around her,She is quite rude,arrogant,and a very unfriendly person.Earlier this year on picture day i got my hair done and she made a rude remark about it "Oh my gosh you actually look decent today!",And couldn't help but notice what she said the the bi-sexual of my class "Boy you know your bi-curious,Nobody will ever like your gay ass self!" after turning bi-sexual herself the day before.Shes 1/4 my size and i could easily kill her if i cared to,But i don't want to start anything or hurt anyone at all.Earlier her friends came to me and told me that no matter what don't try to hurt her that badly and they even warned her that she will get injured badly.I told her friends im not going easy if she comes after me first,She still insist on continuing this.I have a feeling something will happen soon and i need to have self control to calm myself down so i don't snap and fuck up badly.
<bot>: I call some bitch in my class a putrid little cunt after she insulted me multiple times over a period of time and now she wants to fight,How can i hold back from fighting?
