Here is a short article that the traditional view of 1 in 5 of the population get mentally ill turns out not to be true:
Out of that 83% I wonder how many experienced a substantial period of significant distress and/or functional impairment. There’s a substantial difference between a brief, minor episode of psychological/psychiatric illness and a long term, severe mental illness that significantly impairs someone .

Either way, I doubt most of these cases require treatment of any kind.
For many people depression and anxiety are very serious. I know it sounds rediculous after being psychotic
