What is a Panic Attack???

Is a sudden episode of fear that develops for no apparent reason and triggers physical reactions. You can think that you are going to die or have a heart attack, that you are getting crazy or losing control...But you know my first big pain attack was when I was coming from visiting my family in my country, we hit a big storm on the way here, and i felt my heart beating so fast, I was so scare because i thought that i was going to die. but when i came back i notice that out of a sudden i will get dizzy and scare. I went to the cardiology, got some test done, but everything cam out good. So i decide to call a psychologist and a psychiatrist. I'd been taking pills for over a year. But i can tell you that i still have them but i learn with my psycologist that even though i feel anxious i can be in full control of the situation. So everytime that i'm having an episode i listen some music, I try to do something else to get me busy and i won't have the chance to think about anything else.
