Feeling gas in upper stomach and belch.

Hello After lockdown due to corona fear and anxiety I suffered severe anxiety issues and after a month I suffered stomach issues like heaviness in chest tight chest and stomach bloating. Now these things came down after few days but there was continuing belching. I was feeling inability to belch or gas getting trap in throat, like I was feeling I forcefully need to burp. Now after taking 14 days of rabeprazole and anxiety medicine my only symtom left is.. (I feel like gas in upper stomach I mean above navel, like I feel that when I press that area I belch). Belching is still there but when I press my upper stomach I belch lot that time... (Note:- I don't have heartburn, no vomiting, no constipation, and good apetite also)... Also did Ultrasound all report ok... Plz let me know.. I feel like gas in upper stomach and when I press that area I belch.. Belching problem.
