I have anxiety too and history of gastritis and GERD. In May swore I was having a heart attack and my heart tests were perfect. Upper endoscopy showed I have a small hernia. My new gastroenterologist told me in July to have eight weeks of being diligent on taking my 40mg omeprazole. Because of all of the emphasis on "longterm use of PPIs is bad" I was trying not to take it every day". Here at home GI dr tried to push me into hernia surgery. Mayo Clinic talked me out of it and said just be diligent with your med. They disagreed with the PPI warnings and didn't think I was at risk for longterm use. I am doing SO MUCH BETTER. I am not getting acid reflux hardly at all. Just with certain meals and usually one Tums does the trick. Also figuring out what foods are triggers helps. I had one heart scare end of August and it was a one time episode I think brought on by not watching what I ate. I hope you figure out answers and what works for you. It is horrible to live with.
