                        Please don't let a doctor tell you it is all in your head.  I have been through the same thing.  I have Mitral Valve Prolapse Syndrome and Dysautonomia.  It has been the hardest thing that I have ever had to go through.  I have found a wonderful group of doctors.  What state are you from?  There is help out there, but regular internal medicine doctors don't really acknowledge MVPS.  So find a heart doctor or a MVP/MVPS Clinic.
