i do alot of that. i actually had a counselor ask me before if i did cocaine, which at first i didn't understand. Then he explained people that do often do alot of the same things like clicking and making some of the facial expressions and eye blilnking things that I do as well as the blank, expressionless staring, which I tend to do alot..
I can make myself NOT do these things and make myself create more facial expression as expected, but I have to continually stay aware and do it conciously, trying to keep up with what's expected. Even then I can't quite always get it right, and I often come accross as weird.. and it gets EXHAUSTING, when I just want to be myself..
you'd think a counselor would be more in tune with what is common with aspergers/autistic disorders, but I'm surprised at how much ignorance is out there..
