Re: feeling terrible..dont know whats wrong :(
Chronic gastritis and reflux is no fun, I get that too.
There are options to manage it better, though. You could ask your doctor for some Zofran or Compazine for the nausea, and possibly something for the pain, such as Carafate. Proton pump inhibitors are an option, too, but once you start them it's tough to quit.
Best thing is to find yourself a really good gastroenterologist, possibly one who works at a teaching hospital.
