I'm still working my way through Gabor Maté's book, and I think the core idea is less about individual 'causes' and more about how our entire culture is set up to make healthy functioning seem impossible. He argues that the social and economic systems we live in—capitalism, for instance—actively create conditions of chronic stress, disconnection, and trauma, which then manifest as physical and mental illness. What we call 'abnormal' is really a normal, human reaction to an insane environment.
It's not just big systems, either. He digs into how early childhood attachment wounds, the suppression of authentic emotion to fit in, and the relentless pressure to perform and consume all fracture our sense of self. The book made me look at my own anxiety completely differently—not as a personal flaw, but as a logical response to a world that often feels hostile to genuine human needs. The 'myth' is that any of us living under these conditions could possibly feel 'normal' by the shallow standards society sets.
