My situation at home or sum idk

okay, i wrote a 3 page note for my mom the other day because, okay let’s start from the beginning. i share a room with my 9 year old brother, and i’m 16. okay?
I understand my parents cant buy a bigger house but boundaries. my brother has none.
i change in my bathroom,
I call in my bathroom,
I cry in my bathroom,
All my skin care products are packed in a small box under my cloth because my brothers naive and hides my stuff.
back to my mom,
The other day, she caught him at around 2:30-3:30 am and took his phone,
Now i understand why because he is still a kid and shouldn’t be in his phone as much,
But then she looked at me,
and pulled my phone.
I told her i need to charge it since i’m traveling tommorow morning with my father and other sister but she walked away.
I’m 16,
I’m not my brother,
I have my own mistakes.
now why blame ME for something i didnt do?
i wrote her a note telling her i feel really forced around here because of her attitude towards me and that if she has something she feels i shouldn’t do she could tell me since she’s been literally punishing me for no reason.
She saw it and when i asked her for my ID she told me i didnt need her help since i clearly dont want her around.
she made it about HER.
Seriously? what kind of mom are you?
I vented to you about my feelings and you make this about you?
it hurts me, a lot.
and i dont know what to do because all i can do is cry and move on,
but this happens a lot and i cant take it
anymore
