I've had it where I'm laughing when I tell a really sad story so no one gets how upset I am about it because all they see is me giggling. Sometimes I will be mildly irritated at something and angry comes out. And a few times I've seemed really calm on the outside when I'm horribly distressed on the inside. That's part of the reason why I've been accused of lying about my struggles in the past. Then there's also flat affect where everyone assumes I'm depressed when I'm not.

I have no idea, sorry. I've tried explaining to people when the wrong affect comes out with what I was really feeling inside, but I'm not sure they ever believe me. People tend to believe body language over words IME.
