I often say that rebellion in kids often stems from perceived injustice. Kids feel justified rebelling because the authorities are unjust. And they're often right. Parents need to ask themselves if they're to blame for their kids' rebellion. I view your case as child abuse. But, in the words of my dear departed brother, "We got thru it the best we could." For some reason that comforted me. Its like first we have to survive our childhood, only to learn they're still trying to kill us.
