Such a compilation is unlikely to be published. There’s a phenomenon known as the Werther effect, in that as soon as suicide is mentioned in the news or popular culture, the suicide rate goes up (presumably as the awareness of it tips those who have been on the verge). As such, news publications have guidelines to avoid mentioning suicide as a motivation (often, the only tell will be a footnote at the bottom of a story giving the phone number of a suicide hotline). If such a compilation came out, it could be expected to trigger a wave of suicides, if not a small but noticeable permanent increase in the frequency of suicide, so I imagine few publishers ok r booksellers would touch it.
