You're not alone. I had the same exact discovery a long time ago and made a few posts about it back in the day. I was chronicly fatigued since the age of 13 or 14. In addition to my adrenal fatigue symptoms, I had panic attacks at work. One day I realized that each time I had a panic attack I had a large about of wheat, like pasta, for lunch. When I went gluten-free it really changed by life.
I would say my recovery really only started after I went gluten-free. I'm still not a 100 % but getting better slowly. Going gluten-free lifted my fatigue in a course of 1-2 weeks. Getting my hormone functions to normal is taking a long time though.
