What are the motifs in Prozac Nation: Young and Depressed in America by Elizabeth Wurtzel?

One of the most ironic parts about Wurtzel's depression and her mental illness is her lack of desperation. Wurtzel is technically a functioning depressive. She is miserable, highly emotional and intense, yet she is not suicidal. Since she does not attempt a suicide, she cannot be institutionalized and have her insurance pay for it. In other words, she's not crazy enough because she's not desperate enough to want to kill herself.
