“I felt like I was dying," said the 52-year-old “Good Morning America” anchor to People. “I couldn't eat or drink. I couldn’t even get out of bed."

In her emotional interview with the magazine, Roberts revealed that she lost about 30 lbs. during her month-long stay in the hospital.

Roberts battled 10 days of intense chemotherapy to get rid of abnormal cells to prepare for the transplant. Her sister, Sally-Ann Roberts, was her donor.
