I'm the same but I find I'm not as bad at work. I do ultrasound and find that when I'm doing my job I can communicate with my patients really easily, I suppose I'm more in control of the situation. Socially I find it really hard to talk to people I don't know, and eye contact always makes me feel awkward.
I've always been shy, though, and at the age of 42 I've woked out strategies to deal with it.
Just remember, MissE that most people aren't judging you, and if they are they have a problem, not you!!
