Having been a neuropsychologist for nearly three decades, I can spot the signs: wringing the hands, chewing the bottom lip, and bouncing the leg. For others, the signs might include pacing back and forth, or fiddling with something in their hands. There are days I feel like I can barely walk and talk at the same time but watching them do all that simultaneously could wear me out. The thing was, they aren’t even aware they were doing any of it, but they were all a sign of a much bigger issue: worry and anxiety. The question is, where do anxiety, worry, and fear come from? And, what can we do about them?
