My Sister is a Mean Girl

WARNING : long and not looked over, sorry for any spelling or grammar errors

I have a younger sister that just enrolled into the private middle school that I used to go to. Now before I get into it, that middle school was the absolute worse two year of my life. People were just snobby and rude to others and it was a school filled with privileged white kids that got whatever they want and not even the teachers would care. I hated it, two years of toxic relationships and my self esteem was at an all time low. Luckily I’m a sophomore at high school and it’s way better and I have more understand of myself and better relationships with my friends.

But back to the problem. I’ve always know my sister was the extroverted daughter and always had a lot more friends then I ever did, which I understand, I normally like being alone and having only a few friends to talk to. But after the first semester of her joining the school, she’s gained a horrible attitude towards me and my family and others. I’ve heard her talk shit about her classmates on the phone and even though we’re sisters and fights can get alittle out of hand, the way she talks and acts is truly nasty. I know that middle school is a tough age and heck, I remember being kind of a bitch during those years, but this is different. Maybe two nights ago she pushed my limit and I finally had enough and went into my room but not before screaming at her. Then after a few minutes of yelling in my pillow I decided to text her about why she had pushed it and asked her why she was acting like that. Unlike what I expected which was a heart to heart conversation with her that would end with a hug, she continued to blame me and saying I was being over dramatic and acting “like a weak idiot”. I confronted her about once she had gone to this school, she was acting rude and it would effect her negatively in high school if she kept up the attitude. She said she could give a fuck and started saying that she liked being mean and all that mattered was all the friends she had SHE EVEN STARTED NAMING ALL THE FRIENDS SHE HAD. Out of this is was in complete shock that my sister was this type of person. I said she was acting like this girl that was known for being a bitch at school and she said she idolized her. I finally told her that when I’m a senior and she a freshman, I wasn’t going to treat her as my sister, because my sister isn’t that type of person and I didn’t want to be related to someone that thinks being mean to people is fine. What I said was probably a little mean but I kinda meant it. I don’t want my sister to be that person and I know neither do my parents.

I don’t know what to do honestly. I tried taking to her about how she was being but it seems like she could care less. I want to care about my sister but it’s hard when she the type of person that would treat you like shit if she wasn’t related to you.

Sorry this is long but i kinda needed to vent
