Help with Breast Cancer Bills

In 1999 my wife was diagnosed with breast cancer.  We fought the cancer for three and a half years only to lose her on March 13, 2003.  By that time we had lost our home, property, cabin, retirements, cars everything fighting the cancer.   When she died I was over $550,00 in cancer debt with no retirement.  I have worked for years paying this debt off and am down to about $195,000.  The problem is that I am 61 and a disabled Veteran from the Marine Corps and have lately began feeling like I will never get it paid off.  I know this is a lot of money but maybe if enough people could find it in their hearts to donate a little I can get it off my back.  I want to thank any and everyone who would be willing to help me with this.  If you have any concerns about the truth of what I am writing please see the book I wrote called "A Man's Torn Heart".  I told our story from my point of view.
