Hey
My mom was diagnosed with celiac disease when I was eight (I'm twenty-six now). I don't know how long it's been since you got your diagnosis; but if my mom is any sign, I think it must get better.
When I was eight, I remember my mom being tired all the time, and almost certainly weighing less than 100 pounds. She landed in the hospital and they did a biopsy and figured out the problem.
Over the next few years, Mom learned how to find and cook food that didn't contain gluten. (It didn't taste good because she isn't a very good cook; but the gluten was never the problem. I'm told gluten-free can be tasty, if you can cook.)
Anyway, she started out skinny, weak, and always tired; nowadays, she's probably 120 pounds, smack-dab normal, and while she has to put up her feet after work, has the same sort of energy any woman her age has.
It took her a while to figure out how to cook, and how to find gluten-free foods. Eventually, she just gave up on the stuff sold as "gluten-free" and ate stuff that didn't have any gluten in it, naturally. We had a lot of rice and beans as kids (I'm autistic and she put me on GF/CF; no, it didn't help. Silly mom.)
Anyway, point being: It took a while, but my mom learned and things just kept getting better for her, health-wise, and easier to figure out meals. I think once your system recovers from the autoimmune damage and you can start to get more energy out of your food again, things really will get better. That's what I've seen with Mom, anyway.
