Well, nearly a week since my last post and I'm feeling mostly better now! I haven't been to work all week as I've been so ill - I did try to go towards the end of the week but felt so ill that I turned around and came straight back. A visit to the doctor confirmed what I suspected - I had the flu. Not any of the scary versions of it going around but it was bad enough thanks!
Today I'm feeling much better than I did - still a little under the weather but I shall be going back to work tomorrow.
