I punched my step mum in the nose and I hit her head with my step sisters milk bottle 3x
Thats terrible. Why get so violent with your step mom?
She needed to stop abusing me.
Relationships with step parents can be difficult but being violent with them is not good. It could damage your relationship with your birth parent and could get you sent away.
You don't understand what it is like living with an abusive bitch. I'm free from this now.
You should have told your biological parent about the abuse. Becoming violent with her gives her justification to treat you badly. An adult would be better at handling this situation instead of taking it into your own hands.
