How to differentiate if am having heart problem or anxiety .am aged 21?

Primary Dr examines: It's the curse of having health anxiety. Normal bodily sensations and abnormal bodily sensations all are perceived as signs of illness, making it very difficult for the patient or doctor to tell when the patient is actually sick (other than suffering the sickness of health anxiety). Patient must teach himself which bodily sensations are normal. College students almost never get heart problems.
