I am suffering from nausea inspite of having medications. Could it be hiatal hernia?

Hello doctor,

Before two years I was in a lot of pressure and anxiety, while I was eating shawarma. After that, I felt that I need to vomit (nausea). Then I went to the bathroom, and I vomited, I felt relief. I thought nausea would go away. After that, this nausea stayed with me like four-month, I started to hear voices like (gurgles, rumbling) in my throat. Sometimes my throat makes like a small bubble very small bubble that I can feel is going big like then it explodes with these sounds, but that feeling is like 1 %, not that big feeling. It is like a sting, and I do not know what is that?

I went to the doctors, and they did everything they can. And in the end, I did Endoscopy (I have hiatal hernia). He gave me anti-reflux, and to be honest, and I tried them all Pantoprazole, Esomeprazole, Omeprazole, Zantac, Rantac, Disflatyl. Nothing works, I am still nauseating. And I was so unhappy, after four months from using these medications I went to a good doctor he said maybe your problem is psychological, I went to the psychological doctor, and she gave me (Cipralex). And to be honest, after a month, I felt here I am, back again. And nausea disappeared. I was on Cipralex for like nine months, and no nausea feeling.

Now the doctor said, lets lower the dose and stop it. I said, I feel fine. It is four-month now since I stopped the Cipralex. And the nausea feeling came back. And I am really scared about that. So I need an answer, I need to explain what is going on inside me. I do not have H. pylori. Everything is fine, and it could be from hiatal hernia?
