I have had stomach issues since I was 23 when I had emergency surgery for a perforated duedonal ulcer caused probably from stress. Horrible experience. I've had EGDs almost every 3 or 4 years since, just to make sure all is okay (and probably so the dr. can make some money.) And a lot of those I initiated since my stomach just didn't "feel right" for me. I'm now 56 with no problems from the EGDs. I have had and sometimes still do have everything you mentioned, but nothing has led to anything horrible. I've been on Nexium forever and take a probiotic everyday just to keep the tummy rumbles down. I have cherry chewable tums (almost like gum) for any breakthrough indigestion. Anxiety will play havoc with your stomach. I do deep breathing exercises and meditation to calm my tummy when it's acting up. My most recent EGD was a year ago, and this time the dr. said not to come back for 5 years.
