A model of suffering Mental health professionals think about this topic far more than we do (assuming the majority of people in this thread are, like me, 'enthusiastic amateurs'.) One might define suffering as 'insult, injury, or psychological harm forced on an individual against their will', so it is recommended (as a first step in combating suffering) to avoid causing even more.
When someone is in a state where they suffer (or are at risk of suffering), it is up to them ultimately to find peace of mind if they can. The best anyone else can do is to try to create structure that helps them achieve this. That is precisely what mental health professionals are trained to do, and I worry that 'enthusiastic amateurs' would most likely cause far more harm than good (as evidenced by the current opioid crisis in the U.S..) This is not to say that certifiably concerned third parties (family, friends, loved ones, etc.) cannot provide a commensurate level of psychological support.
