Jason was worried about me and walked me home from the tube, and stayed over. He was of course exhausted from working on the show all week and fell asleep in about five minutes. I was happy to be looked after and snuggled with - who knew there was a positive side to the cold weather? But I woke up at 4:30 with the brain squirrels going and probably couldn't sleep for an hour, even though I was happy to lie there. It was wonderfully relaxed.

I stayed in bed late but am really feeling worn out and weak today. I hope I pick up later; I'd really just rather stay home all day and sleep. I can't tell what feeling of not feeling good is caused by what right now.
