Oh Chickadee. Here comes loads of sympathy! Poor you. What a nasty thing to have! You just look after yourself and take it easy. Speaking as someone who has a phobia about anything to do with vomiting, this is nightmare stuff for me and I feel very sorry for you!
I read in the paper that you can catch this virus just by speaking to someone who has it, so that's why your handwashing etc didn't work!
Hope you feel much better very soon!
By the way, have just read Kate Atkinson's new book and loved it!
