Elizabeth Edwards 1949 - 2010

"Today we have lost the comfort of Elizabeth's presence, but she remains the heart of this family," the family said in a statement. "We love her and will never know anyone more inspiring or full of life. On behalf of Elizabeth we want to express our gratitude to the thousands of kindred spirits who moved and inspired her along the way. Your support and prayers touched our entire family."

Elizabeth Edwards had focused in recent years on advocating health care reform, often wondering aloud about the plight of those who faced the same of kind of physical struggles she has, but without her personal wealth.

She has also shared with the public the most intimate struggles of her bouts with cancer, writing and speaking about the pain of losing her hair, the efforts to assure her children about their mother's future and the questions that lingered about how many days she had left to live.

Elizabeth Edwards and her family had informed the public that she had weeks, if not days, left when they announced on Monday that doctors had told her that further treatment will do no good. Ever the public figure, Edwards thanked supporters on her Facebook page.

"The days of our lives, for all of us, are numbered," she wrote. "We know that. And yes, there are certainly times when we aren't able to muster as much strength and patience as we would like. It's called being human. But I have found that in the simple act of living with hope, and in the daily effort to have a positive impact in the world, the days I do have are made all the more meaningful and precious. And for that I am grateful."
