Robin Roberts said there was a time after her bone marrow transplant where "I felt like I was dying."
She made the admission to People magazine, which published some quotes from the interview on Wednesday. Roberts underwent the procedure to treat MDS, a rare blood and bone marrow disease, in September.
"I was in a coma-like state," she said of the first few days after receiving the transplant. "I truly felt I was slipping away ... then I kept hearing my name."
The road to recovery has been grueling. After receiving draining rounds of chemotherapy before the transplant, a visibly weak Roberts told viewers from her hospital bed: "My body is so weak but not my mind. YOU give me the courage to keep going."
It has been almost five months since the procedure, during which time her body responded positively. "It's an amazing feeling, each day feeling stronger," she told People.
She has shared her struggle with MDS with viewers since announcing her diagnosis on "Good Morning America" in May. The news prompted an outpouring of support from viewers, including Michelle Obama and Ann Romney.
Fans have watched Roberts hit milestones in the past few months, from the critical first 100 days after the transplant to her first trip home to Mississippi since the procedure. She did a test run at the studio last month, and is scheduled to return to "Good Morning America" on February 20.
"I'm excited to re-join my wonderful 'GMA' family," she said about her return. "I'm also looking forward to thanking YOU ... for your many prayers and well wishes. Your compassion has been an enormous source of comfort to me and my family."
