Heart Attack. Your anxieties can only be answered by careful medical evaluation. If your family doc says you have nothing to fear, that i think your anxiety needs to be looked at by a psychiatrist...Not simply to get meds, but to see what you are really anxious about. "somatization" can be a very disabling problem.
No. You have no risk factors for heart disease. Unless you use cocaine, your risk of a heart attack is extremely low. Stop worrying.
