I can't imagine how traumatizing this must have been for you.
I'm currently with the loop and I'll be reconnected in 10 days. The only advice I have so far is try small servings at a time. I also started a food journal again and I write down what went well and what didn't. So far I have problems with mushrooms, raw veggies and too much oatmeal. In small portions it's ok.
Good luck
