This thread got away from its intent, which happens when something triggers interesting ideas. But back to the core question: Distress-anguish, as the innate signifier of steady-state, higher-than-optimal stimulus load, is a major source of discomfort in our patients, even though it is usually lumped as "anxiety" by them. Although I've been having fun distinguishing between them in therapy, I'm curious to know whether anybody else has done so.
