I went through exactly what you are going through and I totally understand your desperation and your fear of food.
At one point in my 30s I had elimated so many foods from my diet in a desperate attempt to prevent the attacks that all I ate for one solid year was white bread along with chicken boiled in water (chicken soup) made with a dash of fresh parsley and some carrots. I ate this for breakfast, lunch and dinner. I dropped to 74 pounds.
Thank goodness those days are long behind me and I know how to deal with IBS now. I hope no one, including yourself, will ever have to go through what I went through.
