Panic!

I am definitely totally panicking right now...I CANNOT GET SICK! When I picked Bryn up from camp today she wanted to leave before they finished their open house because she had a bad headache and hadn't felt good for the last couple of hours. She has been laying on the couch since we got home and has a fever. How on earth am I going to walk 60 miles next week if I am sick or just recovering from being sick?!?!?! I am hoping for the best and planning to get lots of rest and vitamin C over the next couple of days...
