Not going to happen, because she knows that she is already "the bad guy" in the picture. So everyone, including the therapist, will be NOT on her side.
And she's probably right.
But she's probably more right than you know. All that teen anger? It might look like it's directed toward "mom" but... you have no idea what all has gone on, or where the anger really comes from. She may have some very valid reasons for her anger that you don't know about.
Trying to get a teen girl to "talk" is next to impossible. Even though they spend 75% of their day talking. Know what I mean??
