I definitely agree with what everyone is posting about the grieving process. I'm only in my 3rd month gluten free and still struggle, but I just wanted to bring up another couple of things that made sense to me. The exhaustion itself that goes along with the disease is enough to depress us, but I believe we actually go through a withdrawal process when first going off gluten that is like what someone addicted to drugs feels. Others on this site have reported it too. Maybe that's what you're going through now. When you think about it, it's no surprise we struggle like we do. It does get better. At three months in, I still have lots of down days, but I have some energy now at least 3 to 4 days per week. The headaches are almost completely gone. The aches in my muscles are better too, as is the gas and bloating. While they're not gone, I recognize them coming better and have figured a couple of things that lesson their impact.
It helped my husband understand better when I had him read some of the topics on this forum. He was being very good about it, but he started actually being proactive when he saw that others had some of the same things I was experiencing. Most of us have suffered for so long with this and have been made to feel that it was all in our head that when we finally get diagnosed, we kind of expect miraculous relief. But it's hard. Just take time and let yourself heal. (I know I need to heed that advice too.) I'm praying you will feel some relief soon.
