While Robin Roberts has been missing from her post at "Good Morning America," don't worry -- it's only temporary.

The 52-year-old news anchor, who recently returned to the show following her bone marrow transplant, posted a health update on her official Facebook page, telling fans that she'll return to television screens everywhere starting next week.

"My heart continues to go out to the remarkably strong people of Boston. We stand by you now and always," her post, which has received over 60,000 likes in six hours, reads. "It saddens me that I haven't been able to join my colleagues in covering this important story."

"Last week, in the middle of my Key West vacation, I began not to feel well," the post continues. "Nothing serious, just under the weather. I contacted my doctors and flew back to NYC. They felt it best to admit me into the hospital for a few days. Seems my young immune system needed a little boost to fight off 'opportunistic infections.'"

The anchor has been battling myelodysplastic syndrome (MDS), a rare blood and bone disorder. Along with the bone marrow transplant, she underwent chemotherapy -- a treatment she was also given for breast cancer in 2007. Her recovery has been chronicled on the ABC morning series, where she has served as co-anchor for more than seven years.

"My doctors assured me that this was NOT because I was working or doing too much, too soon," her post continues. "It's extremely common, post bone marrow transplant, to have complications. I'm blessed that mine have not been severe. I'm feeling MUCH better, and will relax at home for the rest of the week. I'll be back on 'GMA' next week ... as my sweet momma would say: 'Good Lord willing, and the creek don't rise!' Miss you and bless you..XO."

Roberts' mother Lucimarian passed away at age 88 in August. The "GMA" anchor had begun her medical leave a day early to travel to Mississippi to be with her in her final moments.

In recent days, Roberts has been Tweeting about her colleagues' coverage of the Boston Marathon tragedy, posting: "Comforting to see @GStephanopoulos & @JoshElliottABC anchoring from Boston this morn @GMA. @SamChampion & @arobach keeping an eye on NYC. XO."

Roberts received a presidential welcome on "Good Morning America" on Wednesday, February 20, after being absent from the show for 174 days to undergo treatment, and also received shout-outs from Oscar-winning celebrities and The Muppets.

"Good Morning America and welcome back, Robin," President Barack Obama said in a videotaped message, sitting alongside First Lady Michelle Obama, who was dressed in a pink, green, white and brown floral top.

"Robin, we just want you to know that the whole Obama family -- we've been thinking about you and praying for you and rooting for you every step of the way," his wife said.

"You've been an inspiration to all of us and we couldn't be happier that you're back here, doing what you do best," the U.S. leader continued. "So Robin, it's great to see you back in that chair and we're all excited to start our morning with you once again."

Roberts' return was announced on February 7. In addition to the Obamas, other celebrities recorded videotaped messages for her as well.

The list included the likes of Josh Groban, Bradley Cooper, Denzel Washington, Quvenzhane Wallis, singer Mary J. Blige, ABC late-night host Jimmy Kimmel, Tim Gunn, Chris Harrison -- host of ABC's "The Bachelor" and "The Muppets," Mickey and Minnie Mouse and other Disney park characters.

"Good for you! Good to see you back!" Gonzo of "The Muppets" says in one clip.
