Yesterday i felt suddenly disoriented and started to sweat feel faint and heart was racing i have felt out of it and nauseous ever since what do i do?

See a Cardiologist: Sudden onset of palpitation , disorientation , sweating , should not be ignored. Possible paroxysmal cardiac rhythm abnormality, transient ischemia and other causes . Start with a cardilogist to make sure these were are of cardiac origin . Then i would consider other possibilities , as infections, metabolic disorders, drugs etc.
