Thanks for writing your query.
After reading your post, it seems that you are having GERD along with anxiety
You can go for an Endoscopy
and H. pylori test done.
Antacid like Omeprazole
40 mg once a day before meals along with Domperidone
10 mg will be beneficial.
Anxiolytics can be taken under medical supervision only.
Following precautions will be helpful in controlling your symptoms :-
1. Avoid spicy/oily foods.
2. Do not miss a meal.
3. Avoid mental/emotional stress.
4. Avoid smoking/alcohol, if any.
5. Drink lots of pure water daily.
