Most antidepressant usage. Many of those people do not have a chemical problem in their brain, they are just unhappy due to all the societal problems. You can't treat social problems with a chemical.
Well that's just not true. Look at alcohol or cigarettes as an example. In fact, these chemicals control populations so well that it pisses off governments to the point where the periodically outlaw the stuff. How do you think the drug trade survives? People literally treat their societal problems with chemicals all the time.
Oh that's me.
I'm tired and bored so I'll share my story.
I was "depressed" because of working an abusive toxic job and commuting 2 hours a day for dimes. While at the same time spending my free time in the doomerism of r/fvckcars
Filled out the doctor's questionaire and was diagonised with anxiety, and depression. I even had the bottle of pills before the hour was even over.
Lost the job, and swapped my pass-time from pessimistic r/fvckcars to more optimistics YouTube/notjustbikes
No more depression, never needed those anti-depressants because it was never a proper chemical depression.
To many doctors just want to medicate the symptoms and never bother to consider the sickness underneath.
