Everyone I know has been through some shit. I'm not positive I understand what THE SHIT is, so maybe I'm one of the ones where it would be noticeable.
If you're talking about depression, I have not been through that. I've helped people cope or get out of it though.
Even the people I've known who grew up wealthy, have had hardships like people dying, horrible parents, depression etc. One of my friends that grew up wealthy had a dad that went to prison and the family lost everything. You would never know any of that if you met them, they looked like a happy, upper middle class person.
I bring up the wealth because even our super duper billionaires with all of the healthcare accessible to them, look like miserable high schoolers at bad parties. This is not a healthy society in any way.
And don't forget this from a russian propagandist in 2015 (archived reddit link):
