Confused about what I am allowed to eat

Ok so it wasnt Gastritis I had but Gerd.  That is most likely what I had 5 years ago they just didnt diagnose me correctly. So I continued eating stuff that was bad for me for all those years! Now I am trying to manage all of my conditions GerdIBSOCDEmetophobia and panic attacks I am having hypnotherapy for the ocd and emetophobia but the IBS and Gerd are no where near under control. I had an alergy test done which said I was intollerant to Egg yolk and white, yeast, cows milk and gluton. Plus I cant eat fatty, fried or spicy foods because of the IBS. Cant eat chocolate or peppermint (my two favs) etc etc. I just don't know what to eat. what does that leave me with?
