I started my volunteer rotation at the local hospital yesterday. I took a Xanax and tried to be calm, cool, and collected. I thought I was doing fairly decent until I met the nurse at the maternity ward. The first thing she said to me was "Why do you look so scared?". People see right through me. I thought it was a big accomplishment just to be there in the first place and not have a panic attack, but I don't want to look scared all the time. Any suggestions?
