Negative Thoughts on the world
According to the National Institute of Mental Health "negative thoughts of oneself or the world" is a mood symptom of PTSD. Holden shows his opinion of people throughout the story, calling most if not all people a phony. Holden shows us he has negative thoughts of people and the world when he says "One of the biggest reasons I left Elkton Hills was because I was surrounded by phonies" (Salinger 13). Holden has negative thoughts on his school peers and also random people he meets on the streets and tends to call them "phonies". A phony is a person who seems fake or two faced. Holden doesn't believe that many people are trust worthy and don't hold the qualities to be considered to have real personality qualities. It is natrual to have this view on some people, but Holden puts everyone down. This could be because he saw his brother as such a good person and never saw him with flaws so he is learning to cope with him gone.
AVOIDING thoughts and feelings about traumatic EXPERIENCES
According to the NIMH, avoiding thoughts and feelings about traumatic experiences is a sign of PTSD. Holden tends to not do things his brother and him did like walking on the side of the street and he always tries to forget things done or said with his brother. PTSD is often recognized when one notices that another often doesn't attend to "Things that remind a person of the traumatic event can trigger avoidance symptoms" (NIMH). When Holden goes home to visit Phoebe he brings up that he likes his brother when Phoebe reminds him in a brutal way that he is dead. Holden held all of his trust in his brother and now that he is gone he is afraid to get close or let anyone in without them dying or leaving him.
PTSD can be the reason for Holden's unusual behavior. In Salinger's the Catcher in the Rye, Holden shows signs of coping issues and negative thoughts which are signs that he may be suffering from PTSD. Through the book we see Holden show signs of coping issues, such as not trusting others, and negative thoughts on oneself or others like calling them phonies. Holden needs help and his PTSD can and most likely will lead to a deeper depression if he does not seek the help he needs. It is normal for everyday teenagers to go through life with some negative thoughts. Due to deep thought and studies, it is obvious that he is mentally ill and needs help coping with his brothers loss.
