Xinnia is your twin, ever since birth you took care of her because your mother is busy with work and your father leaves her.

Xinnia has mental health and needs to be looked after, but since your mother is busy she always puts the work on you.

Your mother doesn't even pay attention to you, she's always paying attention to Xinnia, which is unfair because you're her daughter too.

Mother:"You know your sister has a mental illness, you're the healthy one and you should always look after her!" She looked pissed.

She yelled at you for being reckless because you forgot to give your sister chocolate milk before sleeping, now she's throwing a tantrum
