first best friend

I am a school student.I don't have friends since kindergarten. actually I don't have any best friends and good friends at all and now am in seventh grade and I changed my school and now I have some good friends and one best friend but after sometimes my good friends is being jealous to me because I am also good at study. And now started fighting between me and my friends and my best friend is not my side and then she also started arguing with me but we are still best friends because I don't want to lose her. One year ago she again started arguing with me because I told her to don't talk to my enemies and she said "ok" then again she started talking to the enemies (means jealous friends) I am really hurt by this then I also started arguing with her and then sold this things to my class teacher and then she became an enemy for me and I realised that how toxic she is because she promised me to not leave and no one will come between us . And then our class teacher teach us a lesson and we forcely started talking to each other but not with pure heart and again I asked her to be my best friend and she said " no you are changed now " and then we started having a normal conversation like strangers and now someone has come into my life 💗
