Dear solarpowered
Welcome to HealingWell and the GERD/Heartburn Forum.
I know many people have the same sx as you have and you are right part of your sx could very easily be related to anxiety.
Have you ever seen a Gastroenterologist or had an endoscopy done? I would strongly advice you to see a Doctor for your sx and also you may benefit from a low dose of an Anxyolitic to help keep your anxiety down until you have the GERD under better control.
Again a warm welcome.
