Good Morning America‘s beloved anchor, Robin Roberts has had a very enduring 2012 and while she has much to be thankful for (including seeing 2013), it will be a quite a while before she’s able to get back to work.

Although it was hoped she could do so sooner, sources connected to the morning show say she won’t be able to be back on air until May or June of the new year. Anything earlier than that can affect her weakened immune system, due to her medical troubles earlier this year.

We’re told doctors are pleased with her progress and say she’s right on schedule, but that schedule puts her on the bench for 5 or 6 months … something she’s not crazy about but realizes is necessary.

Sources at GMA tell us … the honchos are hoping that Robin can return as early as February, but we know that’s not in the cards.

Robin had a bone marrow transplant earlier this year after a battle with breast cancer the year before.

May she continue to have a great recovery. Stay strong!
