Groups of people

I have recently learned something new about myself. I have a very difficult time around groups of people. I have literally broken out in a cold sweat sitting in an area where say 25 people are in the same room. My hearing seems as if somebody plugged me into Miracle Ear and intensified the sound. I no longer am able to hear myself think. Then heart rate increases and by then I am in full blown panic mode. Learning this about myself has been challenging but it allowed me the opportunity to establish a boundary. I am able to recognize the feelings within myself and this allows me the chance to remove myself from the situation before a full blow panic attack sets in.
