Hi Mary, hope today sees you feeling a little better.
I had gastritis also, terribly. Any time I would eat any kind of processed food or artificial sweetener in anything, I would wake up in the night in excruciating stomach pain.
Soon, I was in pain during the day too. But always worse at night. Doctors found nothing useful through all the usual tests.
I lost 35 lbs. I had it to lose, but still, I was so anxious and depressed... It was miserable. A bunch of other stressors were piling up too, so it was a vicious downward spiral.
I had zero appetite. But knew I had to eat. I have a child to raise. She was 3 at the time.
Here is what helped me out... I hope some part of it helps you in some way!!
I could reliably tolerate fresh melon and berries and grapes and pineapple, along with bone broth soup with well cooked veggies and beans. And canned peaches. And all natural yogurt. In small quantities. Some days I could only tolerate one tiny portion mid-day.
I ate those few things almost exclusively for a month. I could tolerate the occasional egg. And rice. I used good quality olive oil as my only cooking and dressing oil. No processed oil at all.
After about a week of eating like that, the pain started to lessen, little by little, day by day.
I know that wasnt a balanced diet, so once I could tolerate them I took Vit E, Calcium, Magnesium, Vit D, and B Complex in to account for that. And a combined Essential Omega Fatty Acids supplement.
Eventually I could add back high-quality ice cream with all natural ingredients. And real butter. Once I added those, my appetite started coming back and I could add back anything but highly processed foods.
That was about 6 years ago. I have none of that any longer. Thank Heaven!!
Prayers for you, I know it is miserable!!
