Not sure of the value of this tidbit but I heard that in the US, blacks suicided a lot less than whites (quick google seems to say rate of black suicide is a third of white) and it could be because they grow up explaining their issues with external factors, while the whites have no convenient escapes, and even are told they are privileged due to their skin color... so self blame.
Really flimsy, I am not an expert but... fits a bit the idea that just looping around yourself self introspecting how much of a failure YOU are might not help.
I would offer the really flimsy statement most blacks in US are descendants of slaves, who were bred for generations to be optimized for unskilled labor that was given very little mental and health support which meant anyone slightly suicidal just killed themselves off. Slavery is pretty stressful. Society tends to want to ignore the fact the colonists and early Americans literally bred slaves under stressful conditions for centuries and that tends to have ... effects on the genetic pool particularly in remarkably stressful environments where risk factors can cause rapid attrition from reproductive population.
I think a more plausible theory is that white people feel more entitlement than black people, not because of some weird genetic memory thing but because they see other white people (or maybe even their parents or great-grandparents) enjoy much higher success than they are. Higher expectations = more pain from shitty circumstances = worse reactions.
This might be true, although I think it depends on the age group of the people committing suicide.
I forget where I heard this, but I believe a significant number of people committing suicide have a high correlation with other issues like chronic pain (e.g., https://pubmed.ncbi.nlm.nih.gov/24916035/) or addiction. I'm suspicious that those white people have the kinds of problems you're referring to because I suspect their peers are less likely to be successful or affluent, as people with chronic pain issues probably are more working class, performing physical labor that results in their issues.
(Granted, I suppose there is probably a racial element that would account for why, if this is the case, more white people with chronic pain issues kill themselves vs. black people with chronic pain issues.)
This is obviously speculation, but so is your comment. I find both to be potentially likely. The scenario you came up with seems more likely for younger people (probably not experiencing chronic pain), and the scenario I came up with is potentially more likely for older people. But we're just spitballing some hypotheses here.
