I am fairly sure that pretending to have a mental illness is a sign of having a mental illness.
Also, there are many kinds of mental illness. Perhaps a person who is depressed and anxious pretends to be a person who cannot think coherently.
Also, as someone who had depression at one point and has an anxiety disorder that is medically treated, but not cured, yes, people with anxiety disorders cannot think coherently. One of the many symptoms of panic includes the inability to use your brain. Think dear in the headlights type stuff.
Anxiety disorders are a part of much of the world, FYI, so people with an anxiety order aren't rare by any means.
I'm not sure how I did that.
