At a picnic with family and friends. I am physically exhausted!   Watching others play ball, I feel shortness of breath, as if I were doing all the running. I struggle to walk to the rest room some 50 feet away from where I sat.

In the evening, I had to take a Tessalon pill (cough suppressant) to get over my cough and my heart felt very slow. As I lay in my bed, I wonder why it is so difficult to inhale and exhale. Have I always felt this lethargic?
