Dealing with drama at school.. MIDDLE SCHOOL?

okay so this is gonna be a pretty long story... so these r the ppl in the story.. Lindsey: the mean one.. Ariel: My best friend WHO IS NICE Alyssa: the girl in my art cl.. okay so heres the story Lindsey always insults me and says stuff tht hurts me. i come home crying to my mom because of her she called me dumb because i have an extra help cl with math and she made fun of my religion too. so Ariel decides to talk to her and says so i heard that melanie (me) is upset because of you at art. Lindsey: Oh nothing happened at art. Ariel: Yes something did happen.. Lindsey: Oh anyways i gotta go but whatever it is shes probably lying... Okay so heres wat happened at art today.. I walk in.. Lindsey stares at me... Lindsey: So melanie are u still mad at me? Me: Oh yeah i still am... Lindsey: *whines* WHY? Me: u should know y.. its because of everything you've done. Lindsey: *sits down upset* Okay so lindsey gets all upset and just starts asking me questions.. Lindsey: Can u tell me why ur mad? Me: *no answer* Lindsey: Are you going to talk at all? Me: No. Lindsey: Will an apology help? Me: No nothing is going to help.. This is like the fifth time you had tried to make me give you another chance.. (i have given her lots of chances and she blew it) Lindsey gets upset. EVERYONE goes around her and gives her the attention and Lindsey leaves my table and so does everyone else and i just sit there alone. I sit there about to cry (AND I NEVER CRY) I go home and Ariel EVERYTHING. Ariel then shows me a voicemail that lindsey sent her... this is wat it said. Lindsey cries.. IM SORRY!! :( IK WAT U R GOING THRU AND... IM JUST SORRY... ANYWAYS I GOTTA GO I JUST WANTED TO LET U KNOW I WAS CRYING... and that was SO FAKE. Ariel tells her to stop talking to me and herself and shes still "crying" and then she texts ariel saying that she asked me if i was okay or anything.. but that.. is NOT TRUE ALL OF THIS MAKES ME WANT TO CRY AND JUST GIVE UP ON GOING TO SCHOOL BUT THAT IS NOT HAPPENING PLEASE HELP ME AND TELL ME WHAT TO DO... please
