BOTHELL, Wash. -- An 11-year-old boy's dying wish to feed the homeless has taken on a life of its own, sparking a movement to help the hungry nationwide.

Doctors gave Brenden Foster two weeks to live. His time was up last Wednesday.

"I should be gone in a week or so," he said last Friday.

On Monday, groggy and medicated, Brenden was having a rough day.

"Tired," he said, visibly weak.

"(You) need some more medicine," said his mother, Wendy Foster, stroking his head.

Leukemia halted the young life of Brenden, who once dreamed of becoming a marine photographer. Brenden has relapsed for the last time. There is no chemo, no more transfusions; just comfort medications.

"I'm hoping I'm awake when he decides to pass because I want to make sure I'm holding him," Wendy later said.

Brenden survived his leukemia long enough to witness his dying wish come true. Last Friday Brenden shared his last wish to feed the homeless.

"I was coming back from one of my clinic appoints and I saw this big thing of homeless people, and then I thought I should just get them something," he said.

Volunteers handed out 200 homemade sandwiches to the homeless to fulfill his wish.

"They're probably starving, so give them a chance," he said.

On Monday, Brenden could barely keep his eyes open as he watched a video of volunteers feeding Seattle's homeless on his behalf.

Over the weekend, his wish went national on CNN. And KOMO News received phone calls from Fort Lauderdale, Florida to Fort Wayne, Indiana.

Clearly in pain, Brenden still managed to smile as he listened to stories about the phone calls and e-mails his story had inspired. His story touched many people from all walks of life, from families fighting cancer to men in the military.

"I think it's great, all over the country..." Brenden said.

"He made my dream come true. In my lifetime, I wanted to change the world and my son did that," said Wendy. "The world is such a beautiful place and (that became) evident the last 72 hours, and Brenden did that."

Brenden has one more wish for the afterlife: become an angel who accomplishes even more in heaven than he did on Earth.

"I don't need to worry about it until the time has come. So I don't bother think about it while I'm still alive; now," he said.

How to help

In Brenden's honor, KOMO News will be holding a food drive for Northwest Harvest and Food Lifeline. You can drop off food on Thursday, November 20th at Fred Meyer stores in Issaquah, Federal Way or Brenden's hometown of Bothell.

If you can't make it in person, you can donate online by going to the Problem Solvers donation page and select "Brenden Foster Food Drive" from the donation options list.

The family is struggling to cover the costs of Brenden's funeral. Donations to the "Brenden Foster Cancer Fund" can be made at any Washington Mutual bank branch.
