I get so nervous when talking to people sometimes that I kind of feel as though I'm having some sort of depersonalization. It's hard to explain but whenever I'm at work and I have to talk to one of my customers I can get so nervous that I can't concentrate on what they're saying. I then space out, and my thoughts begin rushing. When this happens I sort of lose myself within the sensation and I try to grasp what's going on, but I'm quickly overwhelmed with pure fear. I know people can see this, because I can see their expressions, they think I'm weird, and something is wrong with me. Please!! Is this anxiety?!
