A 7-year-old girl in Idaho who's been battling cancer for almost half her life wants to mark her 1,000th day of chemotherapy with cards--from you! 

Good Morning America reports that Zoe Ray hopes to receive greeting cards from all 50 U.S. states ahead of that September 3 milestone. 

"They say they're thinking of me and they share stories of encouragement," Rae says about the cards she's received so far. "It makes me really excited and happy and it gets me distracted opening the cards all day."

Her mom adds, "She says when she's distracted by reading the cards her head doesn't hurt and her stomach doesn't hurt. She'll stand by the door waiting for the mail and just shake with excitement."

On Wednesday, her Zoe Ray of Sunshine Facebook page announced, "Zoe has received 486 cards so far from 26 states plus Canada!"

Cards can be mailed to Zoe Ray of Sunshine, 1930 N. Wind Cave Way, Eagle, ID 83616.
