Stomach bloating/dull pain I think coming from the intestines, short of breath and a full body uncomfortable/weak feeling after eating?

Many possibilities. You sound like you may have aerophagia (unconscious swallowing of air). Other possibilities include irritable bowel syndrome, peptic ulcer disease, cholecystitis, pancreatitis, gastroesophageal reflux disease, diverticulitis, to name a few possibilities. You need some tests to sort this out. Have you seen a gastroenterologist?
