Welcome to HealthcareMagic. See from what i gather, you have vague symptoms like general malaise
, loss of apetite, change of taste, nausea
. These symptoms might be pointing towards some systemic cause or it might be that you just feel them.So I would suggest, you undergo a detailed battery of tests, and pay a visit to a physician. Probably after elaborating your history itself, many things would be revealed.Only after having ruled out organic causes should one think of something psychaitric. So pl visit a physician at earliest.
