The wole approach goes against everything that is known about emotional resiliance and dealing with trauma.
Yes, there are people for whome some terrible experience, or mental problem, means they cannot function normally in life. They may have to avoid certain things and live a circumscribed life. That is a serious mental health problem in the same way having no immune system that functions is a serious health poblem.
But for the vast majority of people, including people with trauma and mental health issues, avoidance of difficult things makes it worse, and exposure makes it better. I have pretty bad social anxiety. My incination is often to avoid social situations. I know from expereince that it makes everything eose in several ways - the more I avoid, the harder it is to put myself out. The more lonely I get, the worse it gets. By not doing things, I don't meet people and find - or really cultivate - places where I can interact without that kind of stress, so isolation becomes even worse. The only solution is to consistently push myself into situations I find intensely uncomfortable and unenjoyable. Over the years I've learned from exeprience some mental tricks to help, that 99.9% of the time it is actually not as bad as I think or even can be a good experience, and even in the worst case scenario, it doesn't really hurt me in any real way. Being uncomfortable, even seriously with a racing heart etc, is ok. Using my frontal lobe to keep that in mind helps.
These kids are not being told this even though psychology is well aware of it, it's not reflected in modern education at the lower levels or parenting, and they never experience it so they remain terrifies and with no practice or techniques to draw upon to help them.
