I heard a doc say that one out of six people have been prescribed a psychotropic medication.
it could actually be higher. I have had the privilege of sitting in front of (40+) patients a day for the last 20 odd years. It's probably fair to say that mental health issues were probably the biggest component in about 40% of my consultations. And to be honest, around about 100% of them, (and my colleagues) have had issues at some time in their life.
The last thing that is helpful is stigmatisation.
Having said all that, the aviation medical authorities do have a duty to not only protect the pilot, but protect the public to.
I'm not a psychiatrist, but there are some slightly concerning features in the post above that do raise some amber flags.
