Thanks for writing your query.
After reading your post, it seems that you are having increased acidity in the stomach resulting in gastritis
It can be aggravated by anxiety so you should continue doing meditation
and exercise and should live a healthy life style and follow some precautions like :-
1. Avoid spicy/oily foods.
2. Donot miss a meal.
3. Drink lots of water.
4. Avoid emotional/mental stress.
5. Donot self medicate especially with pain killers and steroids
6. Avoid gas producing foods like peas, legumes, cabbages,etc.
You can take antacid like Omeprazole
20 mg once a day before breakfast along with Domperidone
10 mg for relief from your symptoms.
Also get yourself investigated for H.pylori.
I hope this is helpful to you.
