FabFiona - I have no advice... but given that we have the same EDD I can somewhat relate to the 'not ready' side of things.
I think your DH is right, you need to focus on you!
... and you're allowed to have 'woe is me' moments. I think its the right of every pregnant woman to have these.

Hope you do manage to take some time out for yourself and that everything goes well for you.
When is your next check-up?
