The night before she entered the hospital, the "GMA" family helped lift her spirits.

Many transplant recipients refer to the day of their transplant as their new birthday.

So on her new birthday, Robin has a message for all of us:

"This journey is as much about the mind as it is the body," she said, in a video that aired on "GMA" today.

"Your thoughts. Thoughts are so powerful. You've got to change the way you think in order to change the way you feel. And let me just say this lastly, I feel the love and I thank you for it. Thank you."
