When i get stressed, i feel sharp chest pain and can't seem to breathe properly. is this normal?

Probably: Chest pain and difficulty breathing are common symptoms of a panic attack. However, for patients with cardiac risk factors (diabetes, high blood pressure, high cholesterol) and those over the age of 40 really should see a physician to be certain these symptoms are not related to a heart problem.

Not normal: Either hyperventilation from severe anxiety, or else angina. Need to consult with your doctor.
