Im exactly the same eat a very limited amount of foods that I rotate every day, I;ve been doing this for 5 years! I plucked up the courage to make myself some banana bread last week, took me 2 days before I plucked up the courage to actually eat some, but I was fine infact I felt really good not bloated at all. Its no suprise we feel this way or have dodgy relationships with food because it ends up not being a pleasure you go through so many years of you eat, your ill, you starve , your ill, food becomes this enemy that makes you poorly. I'm totally in the same boat and just slowly trying to gee myself on.
