I see your point, but honestly, the only way I can respond to your question is with more questions.

Why do we expect deep psychological or philosophical insights to make things better for us, or lead to “improvements”? Why do we think that a profound revelation will bring clarity and resolution to our lives? It could just as well make us more crazy.

There’s the famous case of the “Rat Man”. Whether Freud cured him is up for debate, though he most likely didn’t. But it’s a deep mediation on neurosis, obsession, cognitive dissonance, love, hate. It raises more questions than it answers but it's incredibly insightful. It gets at the heart of human fragility and I think that's something to take seriously.
