Pretty much answer to whatever extent you like. Obviously depends on the culture and time, if we're looking at differences (as im sure suicidal ideation was as common across the board among the comparatively poor as it is today)? Idek that there can be professionals on this topic but if there are id probably be interested in most of your expertise so answer this however you like
/u/sunagainstgold has previously answered How would a Norman priest in the middle ages likely respond to a churchgoer who admits to being thoroughly miserable and tempted by suicidal thoughts? Are there writings/sources from the time that give us insight into how society at the time believed one should fix such problems? and included links to other answers about medieval suicide. /u/BookQueen13 also had something to say. See Was There Any Form of Ritual Suicide Among the Knightly Classes During the Middle Ages? for more.
/u/LateImperial has previously answered In some east-asian countries (China, Japan, Korea, Singapur, etc.), suicides increase during and after university entrance exams. Is this a modern or contemporary phenomenon or there are historical records of similar phenomenons?
EDIT:Sunagainstgold also wrote about suicide during the Renaissance
