You sound like you're doing all the right things. This is my first time writing on this forum - my daughter is 13 and was diagnosed 3 months ago. She is just starting to feel better. The whole family went gluten free even though she's the only one with Celiac. We don't know anyone else with the disease, no one in our town even, so we thought it was only fair that we all do this for her too. The best thing I did was invest in a bread machine. My daughter was a carb-lover before the diagnosis so eliminating bread was not an option. I've been using the bread machine twice a week, making gluten-free breads and experimenting with add ins. I'm not much of a cook but now I've made an effort to become a good gluten-free cook. Most of the breads have been delicious - much better than what you can buy. And someday she'll take the bread machine with her when she grows up.
Anyway, it's been tough, but a learning journey. Now we're just waiting for my daughter to grow and gain weight ! She's got a sparkle in her eyes again so I know she's getting healthy.
Good luck and remember, you are not alone! This blog has helped me tremendously by reading and reading and reading!!
