Robin Roberts is doing her best to stay strong.
With just one more day of chemotherapy until a day of rest leading up to Thursday morning's bone-marrow transplant
, the Good Morning America
anchor, 51, is maintaining a positive outlook.
"The start of last week went well, but the daily chemo/treatment caught up to me by the weekend," she wrote in her Robin's Journey blog
on Tuesday. "My body is so weak, but not my mind. YOU give me the courage to keep going."
Roberts, who is treating her myelodysplastic syndrome, will receive the transplant from her sister, Sally-Ann.
The newscaster, who took extended medical leave
starting Aug. 30, lost her ailing, 88-year-old mother, Lucimarian Tolliver Roberts, shortly after her departure.
"Last Sunday, to lift my spirits, I threw a little party at my apartment for my 'GMA' family," Roberts also wrote in her blog. "The next morning, I walked through the hospital doors, with my guardian angels – mom & dad – back together and blazing a trail ahead of me."
