I wanted my note to sound grateful, but the words couldn’t mask my sorrow over my alienation from any familiar or valuable path. I had lived through transplantation of a stranger’s stem cells into me. The mandatory one year of donor anonymity had passed. Surely I must send thanks to the donor whose cells were keeping me alive. But three years swept me back and forth from the hospital, trying to survive infections and graft-vs-host attacks. I saw my husband’s head shake “no” to each next draft I attempted.
