Fair enough. I was perhaps extrapolating from my (very) personal experience that such is the case, so can provide no hard numbers. It does stand to reason, however that, given a random sampling of people who feel their emotional issues are severe enough to seek mental health treatment and a random sample of people who are not seeking mental health treatment, that you are likely to find a higher incidence of ALL signs of mental illness, including suicidal ideation and intention, in the sample that is seeking mental health services. I would also point out that in my (very) personal experience, it is entirely possible to be suicidal without the people closest to the suicidal person knowing, and it is possible to be too depressed to do anything about it. I would hypothesize that such may be the case with at least some people who commit suicide shortly after beginning a medication regimine, but of course research would be required to test said hypothesis.
