Stomach issues due to anxiety or depression?

It's been 9 long months with little to no relief. It all start 3 months after my grandfather passed away. Woke up one day feeling like I couldn't catch a full breath which led to my first panic attack ever. Chest tightness all day everyday, then I felt weak all day, headaches, lost weight in a short month.i had 2 endoscopies which and got diagnosed with gastritis due to h pylori got treated and eventually eradicated the bacteria. But ever since then my stomach hasn't been the same feels like it has a mind of its own. Been to the doctors so many times even had Ct scans and nothing. Is this anxiety and depression which I got diagnosed? I need help. 2 weeks of 25mg but dont feel a difference.

Stomach issues

Hey, i just posted on this forum with a similar problem.

I got glandular fever 11 months ago and im still recovering. However i have constant nausea tummy tenderness and lack of appetite, all of which are worsened by stessful or upsetting situations. Ive had loads of tests and they have come back normal, so i was thinking maybe my nausea is caused by anxiety and stress

But i dont know who to talk to about thissad
