Can anyone help about my problem?

Hello.

Some years ago I Poisoned and had nausea and because of a special stress I sense that I have nausea all times. For example, When I want travel or use bus and visit new places alone then I am nauseated and it is so hard for me. I visited a Psychiatrist and he Prescribed some pills like Sertraline, Fluoxetine, Alprazolam and...I used these Pills and I'm better but when I discontinued these pills my behaviors backed too many years ago. What is my Sickness? Recently, I visited another doctor and did Urea breath test and Doctor told me I have Gastritis but can it my Sickness? If it is my Sickness then why when I use  Sertraline, Fluoxetine, Alprazolam then I'm better? Can Gastritis cause nausea?

Please advice me.

Thank you.

Any idea?

Yes gastritis causes horrible nausea and pain. It also sounds like you have anxiety issues.

Thank you so much. My anxiety issues apperead when I Poisoned and after it I guess I have nausea always. Just I visit a Doctor about Stomach and solving my gastritis can solve my nausea too? Or I must visit another doctor about Mental issues too?
