i am 20 years old and i have some chronic stomach problems.Is it possible that root cause of my anxiety,depression,nervousness,irritability,agitation ,feeling weak,could be some stomach disease or infection?Is there any chance?I am noxious very often,i have gases,too much saliva and bad taste in the mouth,in the morning my stomach is always irritated and between meals .I sure if somehow my stomach would cause all this mental and physical problems and i would manage to treat it,the i will run naked on the street ,that's how happy i would be
