Thanks ladies. It's good to know I have so much support on here.
@francesthecat, that's very good advice! I've been doing that pretty well up until now (although time moves at a snail's pace doesn't it?) trouble is with the scan so close it's harder. People keep wanting to plan things.

I'm being a terrible wife. My husband made an innocent comment about a Christmas party we have on the weekend and I just snapped 'I can't talk about anything past wednesday'. He mentioned getting a new car and that I should drive a 'big family car' and I said 'please don't talk about big family cars right now'. He's anxious too. I just can't act like a normal person right now.
