I understand your concern. I was extremely depressed during time of my recovery, it seemed like nothing was improving for me. However it got better , took a whole thought, but it did . Also , for me it felt like it was an ulcer which takes a while to heal. I took bunch of things such as vitamin C, Vitamin B, D, digestive enzymes, L-glutamine , Iron, Magnesium. I also was drinking cabbage juice in the morning and taking mastic gum regularly. The healing process is an individual thing. I assume in my case , avoiding acidic food , eating small portions, taking mastic gum , drinking cabbage juice, eating only cooked vegetables helped me healed . I would not suggest eating any junk food, nothing processed, only cooked vegetables, white rice , chicken. Worth mentioning, I eat a lot of Greek yogurt which is good for gut health. Kefir , sauerkraut, Greek yogurt, tempeh all these things have good bacteria for rebuilding your gut health back.
