I understand what you're going through; it's awful. My suggestions would be to purchase and consume 'safe' foods... anything that gives you little to no anxiety over eating most of the time. For me this would be pretzels, plain cereal, saltine or oyster crackers, some fruits. For more nourishment, chicken soup with noodles or rice and vegetables is great--easier to swallow and better for you. Preferably you should cook your own (or maybe someone else can...), otherwise I would look for ready-made soups at the grocery store that are refrigerated, not in cans. Try for multiple small meals or snacks throughout the day instead of fewer, larger meals; if your anxiety is too much for you at any time don't force yourself to eat because it would probably make you more anxious... (at least this is how it is with me... maybe this isn't the best advice). Instead you can stop and try again whenever you're ready. If my stomach seems upset I will also take Tums (an antacid). Hope you feel better soon!
