i absolutely have difficulty reading facial expressions. I tend to read a lot of hostility in people, and it's always been so. There was a previous study several years ago showing that in a test between bipolar teens and non-bipolar teens, showing them faces of different emotions (in photograph,) non-bipolar teens identified neutral faces as neutral and bipolar teens identified neutral faces as hostile.

Also, my face often doesn't read my emotion to others. My husband often asks me why I'm angry when actually I'm not angry at all. I have pictures of me as a teen with that weird angry face, but actually I wasn't anry at the time. He also teases me that I get "zombie" face, which is like a blank face....
