Today has been much better. I've been able to eat, for a start, and haven't had intestinal cramps. Go me. I've just been crashed out on the sofa in front of the TV, being generally unable to face much else. Using the computer was too much effort earlier.
The Visitors scheduled for this weekend have postponed, which is a shame - I was looking forward to it. And I'm at the point where I can lounge around doing nothing and then think "I'd have been able to cope," and I feel guilty. And then I think about actually Doing Something and realise, um, no, I really couldn't. Not at the moment.
Thanks for all your kind thoughts over katlinel-way.
