Occasionally, each of us has a day when we feel "off," when our capable, confident, focused and decisive selves seem to go AWOL.
Usually we can chalk these episodes up to something specific—a cold, a bad night of sleep or some other temporary issue. But what about when that off day turns into an off week? Or an off month? Or even an off year? We may start to wonder—with understandable anxiety—what ever happened to the person we used to be.
