I was diagnosed coeliac 2 years ago and I still resent it.
The only meal I have difficulty with is lunch. I used to have a slice of bread with soup or a salad but gave that up, as GF bread was disgusting and, to make matters worse, a slice was the same or more carbs as normal bread but only half the size.
For the most part, I only have a slice of bread on a Sunday, toasted with poached or scrambled eggs. The best bread I've found is M&S or Warburton's GF. I generally freeze it and take out a slice at a time. Funnily enough, the Warburton's loaf I got before Christmas was only 9g carbs per slice, so not too bad, considering they're not that small. I even managed to enjoy a sandwich without toasting it! Maybe my tastebuds are changing!
As for other meals, I just cook the same things but leave out the gluten. I don't notice the difference between normal pasta and GF pasta, but my husband says he notices. He says the same about GF tortillas!
My husband complains about the length of time it takes me to do the weekly shop. This is because I now have to check the ingredients for gluten as well as carbs. To make matters worse, my sight isn't as good as it was, due to cataracts, so I have difficulty reading some of the labels.
I hate going out for meals as I can never be sure that I'll be able to get a decent one. I've only found one place where there was nothing to eat, so my lunch consisted of a decaf latte. A couple of other places had only baked potato with butter or a salad.
It does get easier. I still haven't accepted this diagnosis fully (probably because being GF for 2 years has made no difference to the one thing I was told was a symptom, so I'm now waiting for test results checking that my pancreas produces certain enzymes necessary for proper digestion of food.) However, I am getting used to it and don't get upset the way I used to when a cafe or restaurant can't cater for me (or don't know how to, which is worrying).
It's unfair, but that's life and we've just got to get on with it.
@Saeeda are you going carb free for all meals or just lunch, the same as me? There's no reason why you should have to do this. The main carbs for meals are potatoes, rice and pasta. Pasta I've already mentioned, and potatoes and rice are naturally GF.
I haven't tried GF cereal for breakfast, other than GF muesli. I've been taking porridge for breakfast for years, so that hasn't changed (except it's now GF porridge) and I take muesli away with me on holiday, so that I know for sure I'll get something in the morning.
It will take time, but you will get used to it. Hopefully you'll accept your diagnosis quicker than me . . . I hope so!
