My friend studies psychology, but she never mentioned AvPD, SA or a lot of other stuff. So I don't think that ordinary people know what that means. People know what means depression, shyness and they stick these problems to us.
A person can usually (but not always) recognize when another is feeling uncomfortable socially, but I'd agree
many people are too self absorbed to really care or think twice about it.
I completely agree with dooby duck. I didn't even know what it was until I got it (or it got worse). I reckon people just think im extremely shy, boring and possibly weird for never going out. Im certain they don't think I have an actual disorder.
