For 'Good Morning America' anchor Robin Roberts there is finally light at the end of the tunnel as she endures a tough battle with a rare blood disorder.

Roberts was diagnosed with myelodysplastic syndrome and was forced to go into hospital to receive a bone marrow transplant. After 30 days in hospital getting over the painful procedure, Roberts has now finally been allowed to head home.

In a frank and honest blog, Roberts insisted that there were still tough times to come. "I am considered 21 days old. That's how long it has been since my transplant. Remember when you brought your baby home for the first time? Your precious bundle didn't leave the house much and you were careful that anyone who came in contact with your child was healthy" she explained. She did add relief that she was back home though, stating "I will still be resting away from GMA until I'm given the all clear, but sleeping in my own bed again feels like a big victory. My doctors will be monitoring me closely and I will still be at the hospital regularly to make sure we're on the right track. I cannot thank my amazing medical team enough. I have a great deal of respect and admiration for how they treat all their patients with such passion and compassion."

She allowed herself to look ahead too, commenting "Each day I get stronger and stronger. I am fond of saying, "This Too Shall Pass." And even 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."
