How does JD Salinger use narrative style to convey meaning in 'Catcher in the Rye'?Use 3 quotes as evidence.

Holden is telling you his story and, through this
exercise, he is able to come to a certain level of understanding about his well being.
He describes his sickness as "this madman stuff that happened to me." At the end of the
narrative he comes closer to full grips with his situation, "... how I got sick and
all". The reader should see certain patterns in the extemporaneous nature of his
narrative. He thinks about things in a patterned way, though these intrusive thoughts
seem to be random. All of his ramblings are rooted in the anxiety that causes his
breakdown.
