had a dieting relapse disguised as healing my autoimmune condition

Back in April I approached a thyroid nutritionist to see if she could help me with balancing my diet a bit better to help heal my thyroid. I was diagnosed with Hashimotos and had gotten to a point where I was so fed up of the idea of being overweight due to my thyroid working against me. I told her I had spent the last 2 years working on my binge eating problems by intuitive eating and told her I’d like to stay close to those principles. She really respected it so this isn’t a case of her trying to convert me to strict dieting or anything but with Hashimotos comes the recommendation of low carb, gluten free, sugar free etc. I had a great first few months, lost loads of weight, my dark skin on my neck disappeared, my brain fog cleared up and I was feeling really positive.

I then, as with all restrictive diets, began to “be bold” and treat myself here and there to some sugar and gluten and extra carbs and before I knew it I was back to bingeing. I stopped going to her out of embarrassment and fear of being judged. Now I’m in a position where I feel like I’m back to my pre-intuitive eating days.

I’m so mad at myself. When I followed principles of IE, my weight settled. I neither gained nor lost weight but I was happy. I had a much better relationship with food and my bingeing had completely stopped for a full year and a half. But I’m so lost because eating low carb and gluten free seemed to help with my some of my Hashimotos symptoms and I have such bad health anxiety that I’m terrified eating “wrong” will make my thyroid/gut worse.

Anyone have any advice or some kind words would be appreciated, especially if you’re someone from a bingeing background who has an autoimmune disease.

Thanks <3
