It also takes younger lives than other disease. When combined with deaths due to "poisoning" (generally due to heroin / opioid overdose), suicide + poisoning cause more lost years of life before age 75 than any other major disease reported by the CDC [1]
Imagine how many more people have attempted or considered suicide, and how depressed these people are, and how much lost productivity is and unhappiness is involved in this
Really tragic how little attention is paid to this
