Do not focus on what she is doing or saying....her voice needs to come at you like it's Charlie Brown's teacher talking. EVEN if it's in an email.
Sometimes you have to put your hands over your ears like a 2 year old and sing LALALALALALALALA....
You can't absorb anything that is negative right now. Shields up! What you take in is what's gonna come out so take in only that which is good and healthy for you.
