<p>OP’s mom is been pretty clear about what she wants: power. This doesn’t seem to be a heat of the argument, or a misunderstanding, or a lack of an intervening adult. It seems that the OP’s mom almost completely uninterested in what OP wants so I can’t imagine that any other human being is going to change that. If anything, bringing a guidance counselor, etc. into the fray will probably just tick the mom off even more.</p>
