Social anxiety is the cause. Meds will stop all the physical symptoms. You still may feel a slight apprehension in your mind but a first meeting will actually be do-able without all the physical discomforts. I was on Lexapro years ago but it made me gain too much weight. Food tasted really good to me and I ate all the time. The best thing about the med was that I was able to complain when I needed to. House cleaning got done. It was a good experience except for the weight gain. I had to be weaned off. Haven't been on any meds since.
