Psychosomatic?

I have decided on a 'duvet day' today. I seem to be doing that rather a lot at the moment. My view is that once the hospital visit is over, I'll be ok, but, until then, I'm hibernating. Reflecting on the weeks before my check-ups over the last couple of years, I've finally recognised a pattern; minor twinges, slight sniffles and a lack of enthusiasm for getting up in the morning. And the day after the check-up, I feel fine.

I think I'm ok, but it always worries me. Five days to go.
