“Perhaps the most profound effect of the new drug was to convince me that I had a mental illness,” Saks continued. “For 20 years I had struggled with this acceptance, managing to hold on to the idea that there was nothing unusual about my thoughts, that everyone’s mind contained the chaos mine did and that others were simply better at managing it…. I wasn’t mentally ill [I thought], I was socially maladroit. Of course, that wasn’t true. There is no way to overstate what a thunderclap this revelation was to me…. But ironically, the more I accepted that I had a mental illness, the less it defined me.”
