I was diagnosed with Celiac Disease almost 4 years ago; was undiagnosed for almost 11 years. It can be somewhat daunting at first trying to learn what you can eat, what you can't, what has hidden gluten in it, etc. But trust me, it's so worth it.
There are a lot of good sites out there that contain a lot of information, just search for it! Good luck, and let me know if you have any specific questions.
