My entitled sister is toxic beyond measure, constantly screaming and giving an attitude to me and her parents,

while also directing this energy at pretty much anybody who gets in her way.

And despite the fact that I've told my parents about this constantly,

they refuse to do anything and even go as far as blaming me for her bad attitude.

And I'm honestly so sick of it and I seriously don't know what to do. Here's what

happened. My sister, who's 15 years old, has always been selfish. Ever since she was a kid,

she would never share. She would never do anything for anyone else, but would expect everyone

to do everything for her. Obviously, as a small child, that is understandable, but she's never

grown out of it. And my parents have always

dismissed this as just her personality. My sister has always been rude to me specifically, and she

demands that I do things for her. She demands I make her food, and demands that I pay for her

things, and that I do this or that, or anything else. But if I ask the same, she just shouts at me.

I don't remember the last time

she's done anything for anyone out of the kindness of her own heart. She just shouts. There's been times

I've been violently ill and bedridden due to a chronic illness, and I asked her if she could get me

some water and she shouted at me, even though I make her food and drink multiple times a day,

because if I don't, she just won't eat.

She's also rude about everything. Anytime someone talks to her, she has a tone in her voice or she

shouts. She is so difficult to have any kind of conversation with. If I say nice things, she's rude to me

and then she screams and it's just awful. And my parents say nothing, but if I dare talk half as bad as she does,

I get told off. I've mentioned countless times the favoritism and how they see her as a perfect

little angel and they coddle her and rarely tell her off and has never given her any discipline,
