Robin Roberts Is 'Home Sweet Home'

(CNN) -- Twenty-one days after her bone marrow transplant, "Good Morning America" anchor Robin Roberts is now recuperating in the comfort of her own home, as she wrote in a post on "GMA's" website.

Roberts was diagnosed with a rare blood disorder in June, but thankfully found a bone marrow match in her sister, Sally-Ann, who helped Roberts through the process along with their other sister, Dorothy.

"I'll be adding that to the long list of things for which I am grateful," Roberts said in her post. "Least of all, my new and improved bone marrow from Sally-Ann. My doctors tell me her cells are making themselves right at home, and with the grace of God, I pray they will continue to do so."

In the meantime, Roberts is going to continue to rest at home on hiatus from "GMA" "until I'm given the all clear," she said. "But sleeping in my own bed again feels like a big victory."

She thanked her medical team, who will continue to monitor the TV anchor to ensure everything's progressing as it should, as well as her fans for their thoughts and prayers.

"I know it is your prayers and warm thoughts that have gotten me this far," Roberts said. "Each day I get stronger and stronger. ... [E]ven in some dark moments, of which there are still a few, I now see that light at the end of the tunnel. This too really shall pass."
