Elizabeth Vargas on 'Good Morning America': "I Am An Alcoholic" [VIDEO]

ABC News' 20/20 anchor Elizabeth Vargas has returned to TV following a rehab stay in the fall of 2013. In her first interview, Vargas is opening up about her alcoholism and recovery.

"I am. I am an alcoholic," Vargas revealed to George Stephanopoulos in a pre-taped interview for Good Morning America on Friday, Jan. 24. "It took me a long time to admit that to myself. It took me a long time to admit it to my family, but I am."

In November of 2013, Vargas first announced that she was getting help for an addiction to alcohol. Two weeks later, she returned home. "Hello everyone! I am home, and so grateful for all your support and well wishes," she wrote on Twitter. "I am so much better and taking it one day at a time."

For Vargas, reaching rock bottom came when she realized that she was "in no shape" to do an interview one day. At the time, wine had become her beverage of choice.

"At night I -- that was a ritual," she said. "I should've realized it was a problem way back when Zachary, my oldest son, was born. And he used to call my nightly glass of wine 'mommy's juice.' You know, and I thought that was hysterical. It didn't occur to me that that was a problem."

Vargas' family, which includes husband Marc Cohn, and sons Zachary, 10, and Samuel, 7, played a big part in her choice to get help. In fact, Vargas claims Cohn had told her to get help before she went to rehab, but she didn't listen.

"'You have a problem. You're an alcoholic,'" Vargas remembers her husband saying. "It made me really angry, really angry. But he was right."

"That's exhausting, to live like that," she explained. "And it becomes very easy to think 'I deserve this glass of wine. I'm so stressed out . . .' I started thinking 'Well, you know, I'll only drink, you know, on weekends. I'll only drink, you know, two glasses of wine a night. I won't drink on nights before I have to get up and do Good Morning America. But those deals never work."

Now, Vargas is focused on her recovery and taking the steps necessary to ensure her recovery.

"I'm part of AA," she said. "I have a sponsor. I have great, great friends who I love and who love me. It's a psychic change, I think. I mean, it's learning to accept that I'm human. That there's nothing wrong with failing, that there's nothing wrong with feeling anxiety."

Vargas will share more of her story on 20/20 on Friday, Jan. 24.
