In an exclusive interview, Good Morning America's Robin Roberts
reveals for the first time that there was a point after her September bone marrow transplant
, "where I felt like I was dying."
It was a few days after Roberts, 52
, underwent the transplant for a rare blood and bone marrow disorder called myelodysplastic syndrome
. "I couldn't eat or drink," she says. "I couldn’t even get out of bed."
Fading in and out of consciousness, Roberts recalls, "I was in a coma-like state. I truly felt I was slipping away … then I kept hearing my name."
Five months later, Roberts, a breast cancer survivor, says she's finally beginning to feel like her old self again: "It's an amazing feeling, each day feeling stronger."
She will return to GMA
on Feb. 20 and will be featured on a special edition of 20/20
, airing Feb. 22.
