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.
