Gosh - thank you everyone.
Suggestions on "decent" gluten free foods would be hugely useful - thank you.
TalbotAMan - you poor thing to have this going on since last year. My own circumstances are completely the opposite. In a nutshell, I have no outward symptoms. Not one. My GP referred me for tests (thinking I had cancer, but that's another story) to the NHS following a single routine blood test. I went privately (DH's work insurance) and in the space of 12 days had endoscopy, colonoscopy and the diagnosis of coeliac.
Maybe that's what makes this harder in my own mind - having never bothered what I eat (and eating everything I fancy), to suddenly not being able to eat most of my usual fare.
My usual diet consists of bread (it would, wouldn't it) and dairy. Toast and cornflakes for lunch, toast (!!!) and crisps with fruit for lunch, and then cooked tea - all sorts of varied things (mince, roast, curry, salad, baked potatoes, pizza, soup etc etc). My downfall is cheese which is my go-to snack (more so than chocolate). I am a rubbish cook, although a good "baker" and do make (or at least did - I haven't tried with GF flour yet) decent cakes/biscuits/scones etc.
I have met with the dietician (yesterday, which is what prompted my post). He (terrified me to be honest) said that unless something is marked as "gluten free", you have to assume that it has gluten in it. Coeliac UK do have amazing lists of everything that is "safe", but I'm reading every ingredient on every item I buy (I would do that before all this happened looking for palm oil which I try to avoid buying, but this is a whole different ball-game). If that's the case, then gluten is hidden in so many things and I'm worried about "slipping up" and having gluten without realising.
Truly - thank you for your encouraging words. I'm going to sign up to Coeliac UK later today.
