Heart health issues

Hello my name is Megan. I am a Nurse, Wife, and Mom of 3 amazing kids. I have been battling with some heart problems over this last year that has really taken a toll on my health and everyday living. I have had some testing done, but I need more done soon. Doctors want me to have a implanted heart monitor put into my chest so I can get properly diagnosed but unfortunately my insurance will not cover the cost of this. I have missed so much time from work due to this. I havent been able to drive in over 6 months, so I have to rely on other people to get me back and forth to work when I am able to go. It has really been a struggle to make ends meet and anything you could give would be greatly appreciated and put me one step closer to being able to get this heart monitor put in so I am able to recieve a proper diagnosis. 

My biggest fear is not being able to get diagnosed properly and something happening to me before the doctors are able to figure it out. My 3 kids need me. They are ages, 3,6, and 9 so they are still young and need their mommy.
