Don't fall for the gluten free hype. Many foods just don't have it anyway. Those that do often have easy alternatives. But yes, you do have to give up some foods. No alternative to that and if you don't, especially long term, you could lose your life to food. Why gamble? Why pay that price and stay bedridden all day? Why let the kids and hubby suffer because you aren't doing what you need to do to manage YOUR disease? They can help. Let them. Teach them and teach yourself. Take the bull by the horns, take charge of your body and your diet, and make the changes. Make them your teammates to stand guard when you have to eat out or shop for food. You need their support and they need you. Be a family and get everyone on board with you.
I hope you can fix this. Right now it's a mess and nobody deserves it to be that way, including husband and family. You owe yourself better than continuing to eat foods that are poisonous to your body. It's not that difficult to protect yourself and let your body heal, but failing to put it all into trying is just setting yourself up for far worse problems later when your body turns on you and deteriorates to its end. Many prayers for your recovery.
