Her last day on "GMA" was Aug. 30 before she started her medical leave. About a year ago, Roberts began feeling the symptoms of her illness, a rare blood disorder known as MDS.
"I have to keep pinching myself and I have to keep reminding myself that this is real," said Roberts from the anchor desk to co-host George Stephanopoulos.
Roberts credited "faith, family, and friends" for her recovery and thanked her doctors, nurses, and colleagues who filled in for her while she was gone.
Even the First Family is glad to see her back. The President and Michelle Obama appeared on Good Morning America Wednesday and said they'd been praying for Roberts.
"You're an inspiration to all of us and we couldn't be happier to have you back doing what you do best," said the president.
