Two things I can suggest:
1) Find out what she gains by her outburst. Why does she do it? Is it attention seeking? Is it for social admiration? Is it frustration?
2) Remember, whatever you have done up until now hasn’t worked, so it’s time to switch methods. Maybe she only responds to tough love. Maybe this is the only way she can get any attention at home. Gotta run now. Maybe I’ll look at this again later.
