I have anxiety for some time now....5 years. It does run in my family. I am only 30 years old and a mother of 2. I thought I could beat anxiety myself but it has been very difficult. Despite 2 trips to the er and numerous visits to the cardiologist I am still convinced there is something up. The doctors have told me the things that I do have are benign and no need to worry. I have frequent PVC's, prolapsed mitral valve, and right bundle branch block. I have had an EKG, echocardiogram, stress test, holter monitor, and event monitor and several blood tests....all which have come back with results that dont cause alarm to the doctors. On 3 occasions I have felt the palpitations, been short of breath and felt faint. The doctors dont seem to have an answer for me except that it is anxiety. I take xanax when I need it...I refuse beta blockers and zoloft which were both prescribed to me. I guess I am just convinced I have an undiagnosed heart arrhythmia that will soon kill me. I have become agorophobic and cant really enjoy things with my younger children. It is very depressing. Any advice would be greatly appreciated.
