Put it this way, it's the first morning for over a week that I haven't wanted to go straight back to bed after breakfast. And although I do feel somewhat drained and washed-out, it is far less than it has been.
I shall still take it easy over the next couple of days and spend less time on my computer each day, but I feel that I am now able to start making my way through the comments, posts and emails. They won't all get answered overnight, but during the next few days I hope to have got through a good proportion of them.
Thank you all for your good wishes, hugs and kindness over the last week or so. They have made me feel cared for and perked me up to see what lovely friends I have (although, of course, I did already know that).
