The previous two days I have found myself i situations of being in very large crowds (1000+). Knowing about this in advance I prepared. I took a small stone - rubbed a hole in it I swear. And I dabbed lavender on my wrist to smell. Both actions I think really helped in managing my anxiety. They still weren't easy situations but I think my preparedness made them less difficult. I have a class tomorrow which I'm a little fearful of and think I will do the same.
