Yolanda Yanez Prosthetic Leg

My sister Yolanda Yanez is 38 years old.  She has heart conditions and diabetes.  After years of battling complications with a diabetic ulcer on the bottom of her left foot Yolanda lost her left leg on May 25th 2014, when the doctors found that the ulcer had gotten infected with gastric gangrene.  We are reaching out for help with trying to raise the money to get her a prosthetic leg so she can walk again.  Any help is GREATLY appreciated.  Thank you.
