I moved out of a moldy basement and the panic stopped, but the burping never did

I was living in a moldy basement for university and when I moved in I had really bad/infected in-grown toenails. I’m still not sure if all of these details are relevant but they may be so I will include them. As a result of living alone in a basement during COVID and never seeing anyone and struggling to walk I started having panic attacks in the night. I took antibiotics and had a surgery done and my toes were better, but the anxiety continued. I went home for the summer and did some psychotherapy and by the time I went back to school in September I was no longer having panic attacks. Sometime about half way through that school year I got sick for a few days and shortly after that I started burping a lot after meals, and then all the time I was burping just small burps, and then I started having acid reflux. I got prescribed a ppi (pantoprazole) and simethicone for the gas. The ppi stopped the reflux but the gas only got worse and it started causing chest pain and heart palpitations. Then the anxiety came back and the panic attacks were horrible. Some months later I started an internship and I moved out of the basement. Around that time I got the hiccups and they never really went away for about a year. It seems perhaps the gas was so much I just couldn’t make the hiccups stop even through the night in my sleep and I tried all kinds of things to stop the burping and reflux. Eventually I stopped the ppi’s and started supplementing with Betaine HCL. This was the only thing that clearly helped and I finally stopped hiccuping after a year and I seldom had any reflux. But the burping never resolved, and still hasn’t. That was nearly 3 years ago. I still burp way too much, and now I get very intense pain in my right side. I need to eat lots of fibre in the mornings to not have intense diarrhea. I have since experienced lots of brain fog and fatigue. I feel so much less sharp than I once did, I have so much less energy, and I feel like my memory is terrible now. It should be noted I am only 24, male, from Canada. I have tried all kinds of things and very little has helped. I have had 3 endoscopies and 1 colonoscopy and all were clean. My blood tests, urine, and stool are all normal. I tested and found a lot of mold in my system but after working with a naturopath for some months detoxing I’m not sure it has helped very much. I burp just as much as before. I also have trouble breathing which I believe is because of the gas pressure which makes it hard to expand my diaphragm fully.
