I'm sorry you're having a hard time with going GF. It is a struggle in the beginning but you will get the hang of it

You need to stop buying pre-made GF food though. Most of it is disgusting anyway and expensive lol Go to a bookstore and invest in a couple GF cookbooks. Also following a Paleo diet is mostly GF as well and have tasty recipes. I have probably 20+ bookmarks of GF blogs and websites that have AMAZING recipes. I have yet to make something that wasn't good! Even the Paleo recipes are good, even brownies!
We don't eat bread anymore mostly because it's too expensive and we can't have eggs. For lunches we do leftovers mostly. When I cook dinner I always make sure there is enough for Colton and I the next day. Breakfast is GF oatmeal, or GF waffles with peanut butter YUM. I suggest investing in a waffle maker! So many things you can do with waffles in a GF diet. You can use them to make panini sandwiches, make breadcrumbs etc. So far my GF pumpkin waffles have been the fav. Even my DH likes the GF recipes I make. Snacks are usually apples with PB, string cheese and a handful of almonds or corn tortilla chips with cheese.
Also once you have an official Dx for either Celiac or non-Celiac gluten sensitivity you can write off the $ you spend on groceries on your taxes! But you have to have the Dx from a doctor.
Here are a couple of my fav places to get recipes :
Gluten-Free Recipes | Gluten-Free Goddess
Health-Bent | Paleo-friendly recipes that don't look or taste like dog food.
Recipes | Gluten Free Recipes (I made her GF green bean casserole for Thanksgiving and ONGosh it was AWESOME!!!!)
Sun Dried Tomato Chicken Bake | Everyday Paleo (this is a VERY yummy dish! I add either goat cheese or mozzarella at the end)
Quinoa Stir-Fry with Vegetables and Chicken Recipe at Epicurious.com (this is really yummy too just make sure you use GF soy sauce)
This should give you a good start on cooking some better meals that actually taste good
Do some research on Quinoa. There's TONS of GF recipes that you can make with it and it's a complete protein!
