Christopher Thomas, 27, was a writer by night and a
teacher by day when he noticed he was always tired and was losing weight fast.
Diagnosed with diabetes(糖尿病), Thomas would need to inject himself with
insulin(胰岛素) three times a day for the rest of his
life or risk nerve damage, blindness, and even death. And if that weren't bad
enough, he had no health insurance.
After a month of feeling upset, Thomas decided he'd
better find a way to fight back. He left Canton, Michigan for New York, got a
job waiting tables, nicknamed himself the Diabetic Rockstar, and created
diabeticrockstar.com, a free online community for diabetics and their loved
ones—a place where over 1,100 people share personal stories, information, and
resources.
Jason Swencki’s son, Kody, was
diagnosed with type diabetes at six. Father and son visit the online children's
forums(论坛) together most evenings. "Kody gets
so excited, writing to kids from all over," says Swencki, one of the
site's volunteers. "They know what he's going through, so he doesn't feel
alone."
Kody is anything but alone: Diabetes is now the
seventh leading cause of death in the United States, with 24 million diagnosed
cases. And more people are being diagnosed at younger ages.
These days, Thomas's main focus is
his charity(慈善机构), Fight It, which provides medicines and
supplies to people—225 to date—who can't afford a diabetic's huge expenses.
Fight-it.org has raised about $23,000—in products and in cash. In May, Thomas
will hold the first annual Diabetic Rockstar Festival in the Caribbean.
Even with a staff of 22 volunteers,
Thomas often devotes up to 50 hours a week to his cause, while still doing his
full-time job waiting tables. "Of the diabetes charities out there, most
are putting money into finding a cure," says Bentley Gubar, one of
Rockstar's original members. "But Christopher is the only person I know
saying people need help now."
