Maybe it depends on culture? I feel I am pretty normal, I don't take medication and I am content (though winning a few millions in the lottery would be nice). Most people I work with are perfectly normal too (and I work at a university in the psychology department, go figure... though maybe that's the reason).

The only one in my family who takes medication is my brother and he has epilepsy. None of my friends take any medication for mental health either or go to psychiatrists. Everyone of us is different but not everyone has some trauma in his past or mental health issues. This isn't a crpg where every protagonists parents got killed by the big evil who was also their grandparent.

I do recognize that mental health problems are far more prevalent than assumed by the general population in past times and that many people have traumas from events in their history.
