This is not a joke. This is not a hoax. This is a real person, a 31-year-old woman from Long Island, who is engaged to be married in October, and who led a 345-city tour to raise awareness of the importance of blood donation, whose liver suddenly failed this week, and who needs a complete liver transplant (Type A or O) to survive.
There are very few of us who might be able to help in finding a liver. But if you know someone who can help, contact firstname.lastname@example.org or go to http://helpshari.typepad.com. Link to the blog, send emails to your friends, send notes of support to her friends and family (via the blog)–do whatever you can.
And if nothing else, pray.
