I find most of the complexity, when it comes to mental issues, to be illusory. Then again, I also think that to some extent, all our ‘conscious thought’ is literally our brain’s ‘noise’ and a result of, not a cause of, most of our actions and feelings and behaviors. Consciousness is fractal, and we tend to overindulge it sometimes. We feel certain things, and the mind keeps trying to organize them into something logical. We fool ourselves into believing that the logical structure we’ve juxtaposed on it is inherent to the system.
