I was talking to my psych the other day, and she asked me how I was feeling; I told her that I was doing pretty well, and that I was pretty cheerful as of late. She pointed out that my face was "out of sync" with my feelings, and that I looked sorta somber and melancholy. When I'm concentrating on something (unless it's funny in some way), my expression tends to go pretty blank and neutral - which is apparently a sign of "I'm sad or angry, leave me alone". Grr, yet another thing I actively have to keep track of - remember to smile at least a little while walking down the street; look away from people every couple of seconds instead of continuing to look them in the eye, lest you look obsessed or creepy; and now, "actively broadcast happiness". Ugh.
