This might be worthless advice, but you ever try probiotics? I've been taking them recently and I feel great. I don't think I have celiacs disease, but I cut down on gluten in the last few years and feel like I have more energy. I get tired and feel bloated if I have a lot of bread, but that could also be from a spike in insulin.
Edit: The only other thing I would mention... it can always get worse. My cousin was in a motorcycle accident in February 1997. He was 18 years old and about to graduate HS. He was working on a mini bike and took it out in the parking lot for a ride. The sun was setting, shadows were long, and there was a rusty, unmarked chain he rode into. It crushed his larynx and he didn't breathe for about 12 minutes (he was alone until his friend showed up). He's blind, quadriplegic, had significant brain damage, and can't speak, but he's surrounded by people that love him and God watches over him. Be thankful for what we have while we have it because it won't last forever.
