How does having a anxiety disorder produce the symptoms of a heart attack like chest pain?

Obsessions: It is not unusual for one in their late teens to be pre-occupied with either of two myths. That they might not make it to 21 or they are invulnerable & can act out/challenge danger without consequences. Simple heartburn in an anxious person can be taken as a sign that death is coming soon. These are things a good life coach/therapist can teach you skills to overcome.
