Shortness in breath, pressure in heart, feels vomiting sometimes, dizziness?

Too young to be sick. People at the age of 23 rarely have any serious illness. This should be reassuring. But young people are more prone to anxiety and stress which can produce all types of symptoms like shortness of breath because anxiety leads to hyperventilation which causes symptoms like dizziness and nausea. I would advice you to practice relaxation and breathing exercises(yogic breathing),take slow deep breaths.
