J.S.
I'm not a doctor, but I know that if a behavior is ONlY exhibited in a certain environment, than meds are not the answer. If she's behaving herself at school and only cutting up at home, I don't understand why the doctor put her on a really heavy-duty psychiatric medication, the side effects of which are severe in adults, never mind children.
I would explore behavior mod options with the psychologist. I would discontinue the Depakote......
