Earlier quoted context omitted.
The hate on antidepressants is not because they're not effective, but rather that they're abused by psychiatrists. Ideally, a professional will prescribe them as a necessary helper to becoming (more) mentally healthy whilst tackling the root cause. Most of the time however, it's more of a "here, take these indefinitely". It's like if we took sleeping pills every time we had trouble sleeping. Having said that, I just…
Agree. But sometimes there is no "root cause", the brain is still a mystery. If you had been depressed even when you knew there was nothing to worry about, you would see it differently, because then you deduce that the black cloud is produced within. Chemistry trumps psychology. Good enough chemistry enables cognitive treatments. But to fix the wrong chemistry you need chemistry.
It's not at all clear that chemistry is the root issue. The brain is a synaptic graph that does something. Some graphs can have weird paths that lead to pathologies (maybe bad feedback loops). Chemistry seems like fairly a blunt instrument for bludgeoning a "bad" graph into one that's "better".
Forced habits, like cognitive exercises from psychology, can sometimes rewire the graph by themselves because that's how the brain learns/adapts, but we still don't have a good grasp on how to do this truly effectively in many cases.
That said, the blunt instrument of chemistry can sometimes be useful, particularly if it enhances neuroplasticity, as I think psychedelic research is beginning to show.
