Burning Sensation in the Chest and Possible Case of GERD

Question: I have been suffering from fatigue and digestive problems for the past years, off and on. Most recently, my fatigue has gotten worse, and I am also suffering from chest pains that feel like burning. It is really hard to get up in the morning.

I have have a colonoscopy, barium upper and lower tests, and endoscope, a sonogram, and an abdominal ct. They showed a little diverticuli and some gastritis in the stomach area.

I have suffered with a feeling of nausea, lack of appetite, and a strange feeling in the stomach...Recently I have that burning, too. I had two near syncope events over the past year...Went to a cardiologist who said they were not cardiac..Took stress test, ekg.

This fatigue seems to be getting worse, and so do the chest burning...I also feel like the lining in by abdomen could be affected, and that is causing the burning feeling? I have considered anxiety and depression, but really do not think that it is them....Just that oppressive physical problem.
