Elizabeth Vargas has checked back into rehab to be treated for alcohol dependency just nine months after she checked out of rehab.

According to the Associated Press, the 20/20 co-anchor checked into a treatment facility this past weekend while on vacation. Vargas has said that while she has been overcoming the disease, the recovery process is challenging.

“I feel I have let myself, my co-workers and most importantly my family down and for that I am ashamed and sorry,” Vargas said.

ABC News released a statement about Vargas, saying that it stands “squarely behind her” and although they are awaiting her return, her health is a priority. In November of last year, Vargas spent several weeks in a treatment facility. Two months after she returned to the air, she admitted to being an alcoholic, reported The Wrap.

“I am. I am an alcoholic,” Vargas said.

She has said that the anxiety she dealt with as a child led her to drink. Vargas said she is “committed to battling” alcoholism and grateful for the support.
