Thank you.  I couldn't believe Amy didn't tell her to get help with her anger issues, and you are right, her brother sounds fragile enough emotionally that he could very well be a candidate for suicide.  This young lady and her brother need far more help than an advice columnist can give, and ideally would move in with relatives.  Yes, that might mean giving up private school and friends, but taking the long view, it would be healthier and they'd be better off at Aunt Lucy's in a public high school.
