List a word and three actions to describe Holden's emotional state as he leaves Pencey in chapter 7.

Holden thinks to himself: "I felt so lonesome, all of a sudden." This word, especially, is indicative of the alienation that Holden is feeling as he prepares to leave Pencey Prep.
Holden is seeking the reassurance of a human connection when he goes into Ackley's room and asks if he wants to play Canasta. Holden also asks if he might sleep in Ackley's roommate's bed since it is empty.
Holden returns to his room and packs his belongings. He counts his money and makes a plan to lie low in a New York hotel room before he goes home. He comments that packing the skates his mother had bought him "depressed" him "a little."
Holden, "sort of crying," puts on his red hunting hat and yells "sleep tight, ya morons!" as he leaves Pencey. He could have slipped away silently, but by yelling, it is a form of goodbye for Holden, though no one returns it, underscoring his alienation.
