I think it’s incredibly naive to suggest that 16 year olds are innocent children who can’t be accountable in a situation like this.
My brother at 16 was habitually smashing my mother’s house up. He was verbally abusive and physically dangerous. Everything she bought him he destroyed, she’d replace it and it would happen again. Bedroom furniture, walls, doors, chairs. Anything. She was absolutely petrified of him. He tried to throw my sister down the stairs at one point for intervening.
Yes, there were underlying issues. But that is no excuse for that behaviour, and at 16 you’re old enough and wise enough (unless there’s some sort of cognitive need there) to know you’re in the wrong.
At no point with my brother did we all think “well he’s a child legally so nevermind the adults and how they’re coping with it.” He was out of line, he was told he was out of line.
I don’t think the OP is innocent here, she’s reached the end of her tether and lashed out.
But there’s more than one victim, and at 16 some of the behaviours the OP mentions from her daughter are absolutely unacceptable and she’s old enough to know better.
