Yeah it does sounds like you could well be celiac or sensitive to gluten. I had pretty much all the symptoms you have described before going gluten free. The best thing you could do is go to the doctor and see what they say. Most doctors don't seem to be clued in when it comes to food allergies so if they don't help you should definitely try a gluten free diet and see how you feel after a couple of weeks. Be sure and let us know.
Good luck (:
