Thank you so much for your support everyone. I'm over the initial shock now and in a weird way it's a bit of a relief to understand some of his 'odd' behaviour better. It will actually be more of a shock now if he's NOT diagnosed with it, iyswim? 
chul and vik i'll post on fb group re his symptoms as it feels a bit open to say too much more about it on here
How's the new job going spirael?
dh so hard waiting for the scan, let alone when its late but do try your best not to worry about it like mad - it's only because we expect to have the scan at a certain time that it becomes a milestone iyswim? if we didn't have scans til 16 weeks then you'd probably feel more chilled. (this is what I tried telling myself when A's scan was late anyway!)
big hugs vik you've been doing so well, being strong for everyone. you need to make sure you're looking after yourself too - that's so important. sometimes even small changes can help you feel like life's less of a non-stop battle - e.g. could dh take the boys for an hour or two every saturday so you can have a massage or whatever?
wss has given some great practical advice too. i think the key is to accept that you'll have to lower your standards and go into survival mode for a while.
memph so pleased you finally had the counselling - sounds like a positive outcome. how do you feel now having gone back thru it?
mlic A's v similar to how W sounds at the mo and i'm pretty sure it's bloody teeth here again too 
oh chul sounds grim again there. i think you deserve to eat nice things for a bit longer! plenty of time to lose weight when life's a bit easier!
tsc are you back? was it brill? is F weaned? how's clara? when are you working again? etc 
what are you all up to this weekend? we're going down to brighton but just for the day to see dh's close friend and their new baby and then will have dinner with my mother.
