I'm so sorry for the stress this is causing you. I'm a medical worrier, so I think I can relate. It might help to focus on these thoughts:
#1 - Even most people who get tested do NOT actually have the virus.
#2 - Worst case, if you do have the virus you have a huge statistical chance of recovering just fine. Even in the worst risk group of 80+ year olds with a 15% mortality rate...that still means 85% of 80-year-olds recover. So think how good your situation is even if you had it! (I've presumed you're under 80 based on your mention of children.)
I am not someone who thinks the virus is no big deal. To be honest, I am shocked by the sad reactions of posters when
DCL cancels cruises and believe everyone should cut as much "public time" out of their lives as possible to prevent an Italy situation....but I still recognize the statistical health risk to each individual is very low. Hang in there and try to rest up and let your body kick whatever it's dealing with.
