I Never Promised You a Rose Garden Chapter 21
Deborah's volcano finally erupts. She has violent fit that includes writing a Yri word for "anger" on the bathroom wall in blood from her cut finger. She thrashes and screams Yri and English mixed while they restrain her in a cold pack. When she talks with Furii about the fit, Furii points out that her tantrum had been anger, but had also been fear that she couldn't control that anger. Yet she had found a way to control it by placing herself where she wouldn't hurt anyone else and also exploding on a night when the nurse on duty was one that was compassionate and kind. Even in her sickness and fear, Deborah had found some control for her anger.
The next day she overhears a nurse say that Deborah seems crazier now than when she arrived on the ward. Furii asks her if she believes that's true, and after some thought, Deborah says, "not sicker. Not sicker at all." Part 3, Chapter 21, Pg. 182
