Im Elizabeth Vargas in baghdad. Perugia, italy. Jerusalem. Reporter tough interviews and seeking out people whose stories had been forgotten. Now she invited my colleague diane sawyer into herr home to share her own story of her battle with alcohol.

I am lucky. All i can tell you is when youre in the cycle of this disease, though, i lost sight of everything. Everything. Reporter haunted by crushing insecurity and anxiety that began as a child, vargas says that as a local news anchor she discovered that a glass or two of wine helped soothe frayed nerves. It was like, ah, i finally feel relaxed. All my insecurities would sort of fade back. Reporter a startling statistic. More than 60 of women who have a problem with alcohol also struggle with anxiety. In 2002 she married singersongwriter marc cohn. You know his song walking in memphis. When i was walking in memphis she says she did control her drinking as she was taking care of their two sons, zack and sam. But her drinking was causing added tension in their marriage. He thought i drank too much. Reporter and so she began a telltale pattern, keeping the amount a secret. And even hiding wine under her bathroom sink. Looking at myself in the mirror thinking this is who i am. Sneaking into my own bathroom to gulp down a half cup of wine so i can get through another hour feeling good. Reporter and then came the uncontrolled binges that she couldnt hide from her family in 2012. A very low point. That was our big vacation. And my idea of a vacation was to empty the minibar by drinking everything in it. Reporter her younger son, sam, finds her in the hotel room. I was drinking and sleeping. And i do vividly remember like one afternoon sam standing by my head in the bed saying, mommy, when are you going to get up . I would die for my children, diane. But i couldnt stop drinking for my children. Reporter after this vacation she did decide to try. Her first secret visit to rehab. But a few weeks after leaving she began again. While Elizabeth Vargas says she was never drunk on live tv, the drinking had now started to kro creep into her job. And its on video. I drank that day. Because i just i was shaky. It was horrible. Reporter it was an interview with a famous singer. Your parents are very, very religious. Yes. And you are very open. Open. Do you see how much im struggling to speak . Reporter after this interview word started to spread around abc that something was wrong. But days later she was back on the air in top form. But it was catching up with her.

Elizabeth vargas finally calls her boss at abc to tell him she needs to seek treatment for addiction. I was too embarrassed to tell him that it was just alcohol because i thought it was so unfeminine. Reporter she goes back to rehab more than once. Then in 2014 press leaks forced her to go public with her alcoholism. Her husband tells her the marriage is over. He cant save her from herself no more these lyrics written by her husband years before they met now have new meaning for her. I think that must have been how he felt. Because he couldnt save me. Reporter then finally, her turning point. When she went on one of her first vacations with her sons as a single mom. I dont think i gave anywhere near the thought i needed to give to how hard that would be for me, alone. I drank again. And i ruined it. Reporter with a nanny helping out with her sons, she says she started with wine. Then the only thing left in the house, a bottle of tequila. Then she gets word that the office needs her to record her voice for a report that airs the next day. So early the next morning an abc crew arrives at her rented vacation house to tape her. Its 8 00 a. M. Im drunk. While howard struggled with the while howard struggled with the so while howard struggled with the s i cant say it. I hear the struggle. I hear the alcohol. Reporter she was drinking so much her children, her boys, were terrified with worry she might die and pleaded with her to stop. And even through the fog of alcohol elizabeth says she finally grasped all the ways she had shattered her life. And you get help. Yeah. And you get help. Then you can fight. Reporter abc news agreed to give her one last chance. With the help of a sober coach she starts the path to recovery. One that now includes regular meetings, support groups, and meditation. And then theres the hard apologies to the husband who agreed to joint custody of the children and most importantly to her sons. You cant just say im sorry, im sorry i hurt you, and then you know, leave it at that. Im sorry i drank. Im sorry i scared you. Im sorry that i wasnt there for you. Im sorry. Im so sorry. Reporter tonight her exhusband has issued a statement, and well post it online.

The horror of war has been documented for centuries, but never before like this. A group of american soldiers deployed to one of the most dangerous places in the world, strapping cameras to their helmets, capturing combat from the front lines. Heres my nightline coanchor dan harris. [ bleep ], man. Those are close as [ bleep ]. Reporter in some ways it may look like a video game. But this is as real as it gets. [ explosion ] welcome to afghanistan. Reporter this is the story of a rookie platoon in the armys 101st airborne. Behind that wall, sir. Reporter filmed in a way we have never seen before. Through the eyes of the soldiers themselves. What is that . Is that a camera or something . Reporter in 2010 kyle bouchers unit was deployed to one of the most dangerous places on earth. How did it come about that you guys started filming your lives . The guys wanted to have memories of the deployment. If they wanted to go back years later and say hey, you know, this is what i did. Dateline normandy beachhead, june 6th, 1944. Reporter the tradition of sharing war stories has been around as long as people have been fighting. But it was only a couple of decades ago that we were able to witness war as it unfolded on screen. Behind me is the emergency wing of the third Field Hospital here in the south vietnamese capital of saigon. Reporter first in black and white. Then technicolor. But now with the help of tiny mountable cameras for the first time we can see war filmed by soldiers themselves. [ gunfire ] the concept of a new series on the Discovery Channel taking fire. This is my first patrol and im thinking, its a beautiful country. Up there when the sun comes up im wondering, man, like this is so cool. Reporter kyle boucher was just 22 years old when he left home for afghanistan. Hi, mom. We really didnt have any idea how bad it was going to get. Go go reporter and bad it got because boucher was sent to the Afghan Border with pakistan, a remote talibanheld region called the korengal valley, nicknamed the valley of death by the bulletbattered battalions stationed there. 42 american servicemen lost their lives in that valley. Hundreds more wounded. [ gunfire ] wheres it coming from . I dont know, dude. Behind me. Reporter in the show it looks like you guys are sitting ducks. Incoming fire all the time. Was it actually that bad . Yeah. We were at the bottom of a valley. The taliban could just creep right over the peak of a mountain, drop some small arms fire and rpgs on us, disappear into the mountains like it was nothing. Reporter were people getting hit by fire or shrapnel while taking showers, eating lunch . Yeah, all the time. Hear that bomb come in screaming overhead. Its awesome. Reporter six years later kyle boucher is one of the stars of taking fire. Along with his close friend and fellow soldier j. J. Mccool. Holy cow. These rounds are hitting inches away from me. Reporter mccool was the first in the platoon to rig his helmet with cameras. Suffice it to say the trend took off. For this series the department of defense did have the final signoff on what footage made the cut. This was filmed by us. We didnt have reporters out there, journalists. Reporter their pov footage tells the raw story of a year on the front lines. The panic weve only got two rockets left. Reporter the adrenaline. Whoa. Theyre still shooting. Reporter and some pretty funny pranks. Candy has always been somewhat of a passion of mine. You didnt really have to try and hide something from anyone else because no one in our platoon will steal something, even as trivial as a piece of candy. Mccool. He probably has the best care packages. So when hes sleeping wed, you know, sneak into his boxes and steal his chocolates and mountain dews and stuff. Reporter while there are moments of fear and concern and stress, youre also having fun. And you that like each other. Yeah. We loved each other. We still love each other. Id do anything for any of those guys at the drop of a hat. Reporter woven into that love, the pain of the losses they suffered. Comrades who never made it out of the valley of death. Got hurt. But hell be all right. In my platoon two guys got killed. Ben chisholm and charlie high. And throughout our battalion i think we took somewhere around 30 to 40. It was a lot of guys that got killed. Reporter how did that impact you . I mean, theres really no way to describe it until, you know, youve been in combat and lost your brothers. Reporter do you think you or any of your comrades suffer from ptsd . Yeah, i imagine we do. When you go through a traumatic event for a long period of time i dont see how it couldnt affect you, you know. Reporter boucher says hes learned to cope in his own way. Since his tour hes left the service to become a firefighter, a job where he can help people and still feel that rush of adrenaline. Taking fire for him is a chance to honor his fallen friends. I feel lucky to be able to have my brothers stories told and memorialized forever. Jingle bells reporter it is the importance of sharing stories, one of the reasons why taking fire has partnered with the headstrong project, a nonprofit providing topquality Free Mental Health care to veterans. One of the things i love about taking fire is theyre telling the personal stories of the wartime experience. This is the time in American History where fewer people have served than in any other point in time. Very few people are related or know somebody who has served in these wars. And so its really important to tell those stories. Reporter just last week the headstrong project partnered with the wildly popular humans of new york. Zack ischol told his story of serving as a marine in iraq, while others spoke candidly about losing loved ones to combat or suicide. The posts got hundreds of thousands of responses. In this country there is an incredible stigma with Mental Health and with getting help. The veterans who stepped forward to share their stories with millions of people, all are demonstrating incredible acts of moral courage. I was finding i just couldnt keep anything in anymore. Its leading to us being able to save peoples lives. It was all around me when i was on that other side. Reporter for the taking fire platoon, part of their story, the lifelong bond they forged in the valley of death. In fact, the group just had a reunion. One last gathering before taking fire premieres to the world. Ill never be as close with anybody as i am with those guys. You know, you come home, could look at a guy that you grew up with, and feel like you dont even know him. A buddy you went to war with, its like youve known him your whole life.
