ANXIETY CAN EAT YOU ALIVE!!!

I am so worried about my little Aiden today. She is performing a circus art act at school today, for the kids in Kindergarden and is SO anxious about the performance! I will be attending of course, but in the meantime I know she is freaking out inside! How do we deal with children's anxieties? What can we say to ease it a bit for them? AND if can we find dr.'s to help them deal with their anxiety? To all of those questions I hope the answer is yes...I want her to feel like her self again, love her love and enjoy being a kid:( BTC
