Wdwfan1973,Thanks for the update and I am sure you were relieved to know you have a "bug" and all is not from anxiety. Going home is a comfort for most people so place yourself in the midst of your loving family and let your Mum offer what Mums have lots of - tender caring love.
Use the medicine to help you sleep and consider sleeping in tomorrow morning - your body needs the rest to overcome this assault by the nasty "bug".
We are always here for you.
Kindly,
Kitt
