Is my sis toxic or am I too sensitive ?

When I was in class 7th she said hurtful things like no one likes you or not even our dog etc

Yesterday also she was fighting with me and provoking me, when I shouted back mum asked me to be quiet so our voices don't go out and neighbors don't hear us.

When I shouted because I wanted to defend myself , she said someone came at home and I am shouting and I know I have no respect at home anyway...

I cried she said I am shedding crocodile tears and I am forcing it

She still uses my past against me, I over shared alot with my friends and they turned out to be fake , she used that against me too .

She hit me alot , mum asked her to stop she didn't and said I deserve it..

There was a time I had no friends and would struggle with bullying - she said if I was in your class , I wouldn't be your friend either.

Is this normal sibling behavior ??
