Brenda's Medical Emergency Fund

Hello, my name is Brenda Buck. In 2009, I was diagnosed with Primary Adrenal Insufficiency, otherwise known as Addison's disease, due to the complications of 7 abdominal surgeries, and a Paraesophegal Hietal Hernia. As I had just undergone an emergency total hysterectomy, which herniated, and subsequently required 2 more surgeries within 6 months, I elected not to have a 4th surgery in the same year. 
In 2010, my corporate job, and my health benefits came to an end. I've been able to function well, up until about 4 months ago. I have made 2 visits to the Emergency room just this past week. The amount of unpaid medical bills is now approx. $23,000.
My Blood Pressure keeps spiking out of control, due to the intense pressure on the aortic nerve, and surrounding areas. Now, I cannot eat, without experiencing major complications.
There are some tests that must be run, such as an Endoscopy, Abdominal CT Scan, etc.
I need an immediate and  substantial amount of financial help with this medical issue. I need help with the cost of additional testing and surgery, and the ability to sustain my home while I undergo these specifics of the next few months. I've always lived my life helping others, and now I am the one in need of assistance and support. I appreciate any and all help provided. Thank you in advance for your generosity and kindness.
