my friend is mad at me

omg like sometimes i don't like people twins i love my sister and all but when someone gets mad at her the automatically get mad at me and I'm like why are u mad at me i didn't do anything
but this happend today my friend Joanna got mad at my sister Amy then Katy got mad at her too then they both got mad at me the Joanna stoped being mad at me which is good cuz she nice but Katy is still mad at me Amy doesn't like her but i do like Katy as my friend and she really nice well i find that but i didn't do anything now Katy is bring stuff up the happen like a month ago like live learn a forget u were my friend yesterday and now you're saying silly reason to be mad at me and yelling at me a break for no reason I'm sorry but I'm a sensitive girl and being yelled at for no reason i kinda wanted to cry just there but i cant cause she'll make even more insults even thou Katy is aw full at insulting people but it really upsets me cuz this is like a chain reaction

Joanna get mad then Katy at Amy then me
but happily Joanna isn't mad any more but i just don't like fighting and being walked up to and yelling random insults
like i mean if u don't like fine but u don't have to randomly walk up to me and insult me
