May I Suggest to PLEASE................ lay off your solicitaion of your clinic.... Please try and go somewhere else other than solicitating these people who are searching for someones genuine advice!!!!!!!!!!!!!!!!!!!!!!!!!!!!! People who post .. wait for responses of help.. how sad to know you are on here solicitating clinical people and places.
As for panic disorders PLEASE google panic attacks.. there are some great online sites that help and give great suggestions to deal with panic. I have dealt with it for 20 years. Good luck with you.. you will be ok... keep trying what you find.. you will find what will work best for you. I found the rubberband trick...works great for me!
No, you cannot die from panic attacks and they do not hurt your heart in any way. It just feels that way! You seem to have had yourself thoroughly checked out and have a clean bill of health...GOOD FOR YOU! The panic attacks are very scary but they will not effect your health.
