In J.D. Salinger's The Catcher in the Rye, Holden experiences symptoms of containing bipolar disorder. One of the many symptoms he contains is that the 16 year old can go from being in a calm, quiet state to being extremely agitated. Holden met up with his younger sister Phoebe and told her about how he was going to travel west to start over with his life where no one knows him, meanwhile he didn't want her going with him, she persisted. During this situation he said "'You're not going. Now, shut up! Gimme that bag,' I said. I took the bag right off her. I was almost set to hit her. I thought I was really going to smack her for a second." (Salinger 206). This situation proved how extreme Holden's anger can get to. He was completely calm before his naive younger sister said she was going to be going with him when he traveled west. Holden also went to drop a note off at his younger sister's school and he saw something that made him extremely angry. In this moment he thought "I saw something that drove me crazy. Somebody'd written 'Fuck you' on the wall. It drove me damn near crazy...I kept wanting to kill whoever'd written it." (Salinger 201). A bipolar individual also experiences sudden mood changes, some more severe than Holden's. A bipolar individual can be in a calm situation whether it be at home with family or it be in the middle of a grocery store, something can trigger this out burst. The outburst are not always involved with anger, a bipolar person can experience manic episodes of sadness, anger, or possibly bursts of happiness. (NIMH). Holden and a bipolar individual are very similar because they both experience extreme mood changes, both Holden and a person suffering from bipolar disorder also do not notice how extreme and sudden their mood changes can be. Holden experiences very sudden mood changes in calm situations or when something could take away the innocence of a young one. Extreme agitation is a symptom of having bipolar disorder. Which is why Holden should be diagnosed with this mental disorder.
