Panic attacks may feel as if they are coming 'out of the blue' and sudden, but they are a response to something going on within that causes fear. It takes time and work to be able to slow the process down so you can catch where it begins and learn what it's about. Learning this means you don't have to mute it or numb it with medications; you learn it will begin and it will end and in the process there is much to learn about oneself. The more you learn and understand, the less intense and then less frequent the panic comes.
