bully?

So yea yesterday was october 23 2015 and i went to a football game. i was walking on the edge of the field with two of my "friends" and a girl lets just call her Casey, well she walks up to me and calls me a lying bitch and pushes me and i tell her to get out of my face, after i say that she again pushes me and starts hitting me so i pull her hair and she like freaking punched my nose so i punched her in the stomach and she just keeps hitting and calling me names and what trips me out is there is just this old lady and i guess she just is one of the staff and she just stands there and doesnt say or do anything she just watches, then Casey pushes me up against the fence and we just separate and we just walk away. the worst part is that one of my "friends" video recorded it and gave it to Casey and didnt even help me, and what really pisses me off is that i left that school for all that bullshit and i go to one home game and i get beat up because im a lying ugly whore? fuck no. im done that was my last straw i really just want to kill her but i wont because its not worth going to jail, but i just wish that... idk anymore i just want sleep
