ABC News’ 20/20 co-anchor  Elizabeth Vargas has checked herself in to a recovery center where she is being treated for alcohol dependency.

“While on vacation this weekend, I decided to return to a recovery center,” Vargas said in a statement. “As so many other recovering alcoholics know, overcoming the disease can be a long and incredibly difficult process. I feel I have let myself, my co-workers and most importantly my family down and for that I am ashamed and sorry. I am committed to battling and addressing this debilitating disease and want to thank everyone who has offered their unwavering support during this trying time.”

Back in January, before returning to  20/20, Vargas appeared on Good Morning America to talk about her previous treatment in a facility in fall of ’13; in that interview, she said it took her years to admit she is an alcoholic. A book she is writing about her experience with the disease is scheduled to be published in the spring.

“Nothing is more important than Elizabeth’s health and well-being and we stand squarely behind her,” ABC said in a separate statement, issued late Sunday, adding “Our thoughts are with Elizabeth and her family and we look forward to having her back at ABC News when she feels ready to return.”

Vargas joined ABC News in 1996 after working at NBC News since ’93.
