I haven't been exposed - that I know of. We were with a lot of family members over the holiday weekend, though. I know what you mean about false alarms. I feel like I spend so much of my life preparing for things that never happen (thank goodness)! I'll try to keep in mind what you said about the worst thing ... and that it doesn't last forever. I hope you are able to get some rest and feel better in the morning. (Ana: I love your saying about "not giving up"!)
