Have you as an adult ever come to the realization that you were abused as a child when you thought it was just normal? Like being beaten?

It was more mentally abusive then physically. Although if I lost a fight at school with someone, my brothers would beat the snot out of me for losing before they went after the other guy. Then Dad would give us all a hiding for fighting.
Mum is a malignant narcissist, her gaslighting was truly next level and it really did a number on us. Drugs, suicidal, ran away from home.

But can't complain. Plenty of others had it much worse.
