Panic attacks are hard enough to deal with without your chest having all the pressure because you are sure you are going to have a heart attack. Everyone one says exercise it helps no it is just as bad if not worse mentally because I fireside am going to die then. I am well aware it is all In my head but WHAT IF. Is what gets me every time because you never know you can have a healthy heart one day and have problems the next. Oh my I am just out of control please xanax work soon oh please
