So, basically you're right, this is the way to be able to get away with thoughts from the fear. But not always it can be done. The situation is a little bit better when the event which is in a large hall, does not require so much concentration. But as I wrote, soon I've an important exam at the end of my vocational high school, and it requires from me during this exam to keep my head free from bad thoughts, any anxiety and fears. No way, about getting out of place, unfortunately, because at this time I lose my exam. Also too long trying to "relax" during a panic cannot occur, because I must act quickly and try to break the barrier with my fear thoughts (beat them) to find the free way to think about the content of the exam test. And on that battle I always lose...
