On Jan. 31, 2009, I had a rare fourth bone marrow transplant. This is my story of running into a diagnosis of Acute Myeloid Leukemia, or AML, in 2003 after feeling unusually winded while running a 10K race. It is a story of falling down and getting up and falling down and getting up many times over, with two relapses, life-threatening complications, life-long side effects... and a determination to keep moving. I am a freelance writer with a background in daily journalism. I have three children, one Labrador retriever and a debt of gratitude to my bone marrow donor. I have written versions of the story for The New York Times, The Philadelphia Inquirer, Espn.com, Marie Claire and Vice Media. I started the blog in 2008 with one story and found that I had many more to tell.
