"Thank you for your prayers," she says from her hospital bed.
"I haven't gotten up and walked yet but that's coming in about an hour.
"I just love everybody. I just thank my family and all you guys [for your] prayers out there and all the calls I got. I really appreciated and I couldn't have made it without everybody, so thank you so much."
