Does Holden kill himself?

Holden does not kill himself in the novel but definitely mentions suicide several times as his mental struggle plays out in the story. In fact, there are clues that Holden narrates the story from a mental institution when he first mentions that he “felt so lonesome, all of a sudden” and “wished [he] was dead” and that he “felt like jumping out the window” after his big fight with Stradlater in the Pencey Prep dorms. He mentions suicide multiple times while in New York City, once after his altercation with the prostitute and Old Maurice, saying, “I felt like jumping out the window. I probably would’ve done it, too, if I’d been sure somebody’d cover me up as soon as I landed.” Even though Holden teeters on the brink of dark depression and suicide throughout the novel, he ultimately seems to grasp how to survive, looking for ways to come back from his mental breakdown.
