Waiting for a slightly overdue baby is an interesting experience. I mean that in the Firefly sense.
It's the "should I start this, or wait?" problem. At any moment you might have to drop whatever you're doing and disappear off to hospital (or more likely, disappear off across town to home and thence on to hospital).
Don't start that bit of work; ignore those friends; don't do that DIY; life on hold while you wait.
You get anxious. Jumping at the phone when any call could be the one. Anxiety bleeds over into the rest of your life and makes you snappy. This gets progressively worse as time goes by.
So there isn't much advice here, just a case of: be aware of the waiting is having an effect on you.
