My sister-Why?

Follow up thread to "My sister Gives Me Anxiety" to She doesn't even care- she says its all MY fault. I am annoying,disgusting, immature,& weird. She asked why I was wearing this outfit, & was rude about it. She said she wanted to have a happy life, so thats why she corrects me. She wants me to dress like the "popular people", wear makeup, go to upscale stores, wear the cutest clothing. She keeps telling me to straighten my hair, & wear makeup. I tell her I do not want to. She keeps telling me too. She is judgemental.

Once I used her toothpaste, & she kept saying I nasty animal.Another she said I pedophile. She says I have no manners, but she does the SAME thing.

I asked her if she could say anything good about me, & she said I don't know. She brags about herself, & also says she is always right. But denies it.

How old is she? It sounds as though she's in the high school years, in which case she (should) eventually outgrow that mindset.

When my sister and I were in school she was known by many other students as "Trebyn's sister", and it annoyed her a lot. People she didn't even know would go up to her and ask her if she was my sister, and then that would affect how they treated her. As an adult it still bugs her when someone asks her if she's my sister, but that's a rare occurrence now. Out of high school the world is totally different, and you don't get put into categories as much as the clique-ish high school environment. You get to define yourself through your own actions.

Ultimately that's probably what your sister is really mad about. That her identity is not yet her own. That's just the reality of that age though, and it's not your fault at all. You're the target of her blame, but if not you she'd blame parents, friends, wealth, her appearance, the family car, etc. It's her trying to define who she is to the world, but it's unfortunate that you're taking the brunt of her frustrations

One of my own friends was embarrassed by her brother and used to tell people that he was her half brother, even though they were actually fraternal twins. They wound up becoming really close in their upper teens, and she felt really bad for how she treated him.

People have to learn to accept themselves before they become willing to accept others for who they are. It sounds like you have a better idea of who you are than your sister does about herself.

She is actually in 6th grade(middle school).

Ahhh, that's exactly the same year that my sister got into that kind of stuff. She suddenly began demanding only specific designer brands of clothing, had to get a specific style of shoe, listened only to specific music. All of it was because that's what the other girls were doing and she wanted to fit in with them.

Has your sister been doing what she's doing for long? If it's only been in the past year or so that she's been acting the way you're describing she might become more tolerable by the next school year.

And how old are you? Your sister is still very young and testing her ability to have power.
She is looking for attention, trying to be a "mean girl type" too. Don't ask her "why", she isn't going to really be able to give you any real answers to her bad behavior.

I am 16, turning 17 tomorrow.

Since the middle of 5th grade/summer of going into sixth grade. It just progressively gets worse.
