Please talk to your pcp about your anxiety/panic attacks. A good support group like Womenheart (if you are a woman), and the American Heart Association can help tremendously. Your pcp or cardiologist may have access to a good psychologist to help you adjust. Its not easy emotionally to be implanted with a mechanical device so give yourself some grace and be patient. I speak from experience since I have been implanted with an ICD seven years ago. It can be a challenging adjustment.
