Yes, I've been told I'm either very exaggerated or laking appropriate emotion entirely. Apparently, if I'm happy my body language will indicate that I'm Ecstatic, if sad - despairing, scared - terrified, etc.. However, If someone asks me to smile, in a picture for example, I'll grimace at best. And I'm often told I look angry, mad, stone-faced, and that my demeanour needs to be more pleasant. The odd thing is people usually tell me this when I'm feeling most comfortable.
Walking funny, having to look where i walk, touching my face, twitching, involuntary visceral responses, talking too loud, talking too low, talking under my breath, no talking at all when conversation is expected, stimming, laughing, smiling "like an idiot", crying at inopportune times apparently for no good reason... yeah I never noticed it all until people started pointing it out to me. They're right, it's kind of strange and being conscious of it makes it all a conscious effort which just adds another thing to think about.
Hanging out with like people is a sigh of relief. Not only is self-consciousness reduced but noticing similar behaviour in others seems to minimize my own.
