MIL issues again!

I finally snapped we got in a huge argument and lately thing have been better. The issue now is instead of yelling at my kid for every little noise she makes and practically calling her stupid when she doesn’t want to do her school work or when she says she wants to be a doctor. She’s now doing things to try to get her in trouble. When she cleans she just throws everything on my daughter bedroom floor. (Most of which doesn’t belong to my daughter) then she says things like “have you seen her room”
