"I think it's important for any person to own their own story, the good parts and the bad," she tells PEOPLE.
"I first started to wonder if I had an issue, so I read other people's books, and they helped me enormously. It's very scary to put it out there, but if I can help one person feel less alone, then I'm really happy about that."
Vargas will release her first book, Between Breaths A Memoir of Anxiety and Addiction in September.
And as far as the writing process, the 20/20 anchor says there were plenty of ups and downs.
"Partially therapeutic, at times painful, and yet also, at times, very liberating," she says. "This was about admitting what I did, what I suffered with, and how I overcame it," she says.
Vargas checked into rehab for alcohol abuse in Nov. 2013 then returned less than a year later to be treated for alcohol dependency.
"I am really lucky, and every day I realize that more because I see so many people who don't have family and friends who stood by them, or employers that gave them another chance she says. "I am extraordinarily blessed."
Vargas' next 20/20 special about a secret network of people who take the law into their own hands and hide children that they believe have been wronged by the family-court system airs April 8 on ABC. "I've been working on it for months,” she says. “I'm very excited."
