Suicide. Mass shootings. Opioid addiction. All dysfunctional ways to regulate your mood. There are five ways to regulate your mood: avoiding the situation, changing the situation, changing the focus of your attention, changing your cognition of the situation, controlling your emotional response. The listed problems are about changing or avoiding the situation. They make the situation worse.
It would be better to make the situation better. People take these drastic steps because they don't know how to make it better. Nobody ever tells you how to regulate your mood. You're just assumed to know how to do it when you reach a certain age, and you're blamed for not knowing how. Mood regulation is learned. If you don't learn how in your family, you don't often get another chance. It works mostly on an unconscious level, and is difficult to get it to the level of awareness.
But compassion can be learned. You start by wishing people well, like in loving kindness meditation. Eventually you can move to taking more concrete steps, like helping other people with their needs. Second chances are what religion is about. If we can stop blaming people for their mood dysregulation, and instead teach them to regulate, we can really make the world a better place.
