go NOW and buy "The Gluten-Free Bible" by Jax Peters Lowell. you'll find lots of enouragement, tips, etc. i don't know where i'd be without this book.
i know it's hard to stick to this diet, but you need to know that it's not a choice. you already have serious illnesses, why would you want to hurt your health now? you WILL NOT HEAL if you keep cheating...
