Stomach Upset
If you find yourself experiencing upset stomach, you may be suffering from one of the following conditions:
Heartburn/GERD
Heartburn is an irritation of the esophagus that is caused by stomach acid. Occasional heartburn isn't dangerous, but chronic heartburn can indicate serious problems and can develop into gastroesophageal reflux disease (GERD).
Generalized Anxiety Disorder (GAD)
The individual suffering from GAD lives in a constant state of tension and general uneasiness. They are oversensitive in their relationships and generally feel inadequate and depressed. No matter how well things are going, they are nervous and anxious. They find themselves constantly worrying. Typically, at the end of the day they mentally review their daily activities, list out all of their "mistakes", real or imagined, and come up with what they "should" have done in that situation.
