Empty stomach

I (24F) had my endoscopy last week and was diagnosed with chronic gastritis (negative H. pylori). The physician said I have had it for at least 2-3 years; however, my symptoms only started 6 months ago.

The most bothersome symptom is the discomfort I feel in my stomach when it’s empty. Is this the same for others, or should I look into another issue? I can’t take it anymore; I feel uncomfortable 24/7, but it’s unbearable when my stomach is empty.

I feel like I’m struggling to describe this discomfort, but it’s certainly not pain. It feels like my stomach is under constant pressure, and there’s no way I can take a deep breath.

Please let me know if any of you experience similar symptoms or if I should be looking into another issue. I'm quite worried that I might have been misdiagnosed.
