Purple is it bad that I actually feel a teensy bit sorry for your appeasing workmate 
Only kidding - hope you feel better soon. I have these periodically. Last night I was having a 'what the hell am I thinking about becoming a mother' session, lying in bed, panicking that I couldn't imagine myself as a good, calm mum in the face of terrible twos, nagging 6 year-olds and arsey teenagers.
Felt very dark and dreary and couldn't sleep as a result. Then I did fall asleep and got such a whack from BB that it woke me up and snapped me out of it. Think I may have been projecting my worries because s/he wasn't very active yesterday after the scan so was very happy to have BB 'back'.
Today it's back to normal, pummeling me in every direction, possibly even a brief hiccup spell - so have decided it was just peed off at being prodded and poked yesterday morning. That or I was.
Hormones, eh.

As for keeping calm in labour. Well. Cos it's not stressful squeezing out something the size of a watermelon from something the size of a small plum, is it. Should be easy!
