mommy issius or overthinking?

This is my first entry if i made mistake don't mind me :)

So yesterday my mum got so mad and yell at me so i know this is normal but i mean she doent do that to my brother and when she yell at me i cant say a word to her but my brother does idk he raise so different like he does everthing he want he doent need to be perfect but my parents expect me to do everthing even my brothers stuff i have to help him or my parents can be mad 

When we little kid i always took care of my brother i was his half mum ''violet!your brother dont know what is the homework tell him!Violet look after your brother at school!!''they always treat me like this :) (btw my brother and i twin so we are in same age)

My mother hate when ı had mistake even if it is little thing did she told me to bring something i couldnt find it...She find that thing throw it to my face like..ıt really happened she told me to bring the bleach (she was cleaning to somewhere) and i couldn't find it bcs she didnt explain me where is that thing and then she find it she litterally throw it to my face ı am not joking after she did that she told me to clean the mess and she left the house i had panic attack, that day there was so much question in my head it was really bad they and it isn't the only thing she done..

And yesterday almost same thing happened i don't understand am i the bad child or she is the bad mother?

Like she didnt have a good past but the trauma she got doesnt explain anything...

Some of you might say go talk to her or why don't you tell her what you felling etc.

But i didnt learn how to express myself

It is realy hard for me speak about my problems...But i write it.

I hope in here i can be me

I really hope you guys understand me :)
