Transcript for Elle King on some of her darkest times and the music that saved her
Reporter: It was this mega hit that made elle king a star. Her soulful voice and that track earning her two grammy nominations. I went from being nobody and playing really, like, small clubs to, like, the exact -- talk about 180, you know? Reporter: And before she knew it, she was performing alongside country star Dierks Bentley at the cmas. ?????? and for president Obama at the Kennedy center honors. ??? Oh, respect yourself ??? Reporter: But she's done a lot of living since. Now at 29 years old, she's been married and divorced and she's got a second album to tell the tale. ??? You just hurt too much but I'm fine ??? ??? I'll fix it all ??? Reporter: In songs like "Sober" elle revealing her battle with substance abuse and depression. Reporter: You've gone through a journey in the past three years. What have you learned about yourself? I've learned that I'm a lot stronger than I thought I was. I've learned that I can have boundaries and that I can say no to things and to people and that I do have enough respect for myself and my body and my time and my spirit. Learning to say no is a huge thing. A huge thing. And it's really -- it's an uncomfortable thing. I'm getting red in my face right now. Reporter: Elle has learned a lot about herself, life, and love since her brief and she says tumultuous marriage. She met her ex in 2016 and they secretly married three weeks later. But it didn't last. A year later, they were divorced. I think it's been pretty public news now that I had a pretty tumultuous relationship and kind of a not so perfect marriage. And my marriage had started ending early last year, and just, you know, things happened behind the curtain, and it's hard to keep a brave face. Reporter: To cope, elle says she turned to drugs and alcohol. She became depressed and was diagnosed with PTSD. In one post, she wrote, I'm going through a pretty rough time right now but for once, I will not accept or admit defeat. I will get out of bed. I'll take expletive anti-depressants like I'm supposed to. I think it was maybe like I was crying out for help in a weird way. I don't know, I think back to that time and I was just really lost and really scared and I felt really lonely, and I don't know. But the more I talked about it, the more I could start talking. I couldn't even look people in the eyes. I couldn't leave my house. I was just really low, but I tried to not just sit in it. And so I did the best I could where I was at. Reporter: But ultimately, she says it was her band and her music that saved her. ??? I don't need nobody ??? Reporter: When you talk about the last track on the album, "Little bit of loving." Every song hit me like in a different way but that one, you know, it leaves you thinking. And it seems like you really had a message that you wanted to get across there. The problem wasn't out there. The problem was inside of me. But I'm not broken. That song came to me in a really, like -- I was very lost at that time, and I was really struggling with PTSD. Somehow, this song just came to me. I was singing the, like, outro part of that song, which is like big voice singing. ??? I die a little bit of love ??? And it was the first time that I really felt, like this joy in months, and I remember, like, snapping back into my body and falling to my knees and crying and going, I'm so sorry, guys, I'm so sorry. And I looked up, and my bassist, paulie said to me, it's really nice to see you again, el LE. Reporter: What was that moment like? It was tough leading up to that moment, but once it came, it was beautiful because like I said, I've been playing with elle for six years, and -- sorry, gets me a little emotional. To see my friend back with us, you know, the person that I know and care about is great. It was really cool to see that, like, she was going through all this hard stuff and then there was a moment of, like, she realized, one, her music could pick her back up and two, this record could really save her life and I feel like it did. And I feel like we all got to be a part of it. Reporter: Now, elle is back right where her career started, small venues in Brooklyn like rough trade, taking it all in. Are you used to seeing your face on rolling stone yet? Does it get old? It's an honor. If "Roling stone" wants to review your album, it means that people out there who listen to music are listening to your record. Reporter: Her famous father, rob snider, is listening to. This morning on gma, her dad sending her a surprise message. I love you. I'm so proud of you and I'm so excited. Reporter: It's a relationship that's evolved in the years since childhood. When she first made a cameo alongside him in "Deuce Bigelow." What are you watching? Reporter: How has your relationship with your father grown and developed over the course of your childhood and then now adulthood and career? Well, my dad was following his dreams for a long time. We kind of met in the middle and we were like, let's drop all that . I love you. We look alike. I don't know. My dad just showed up for me in such an incredible way when I was really needing him, and we have just become best friends. My dad was pretty big, you know, when I was a kid. Huge. Reporter: And everywhere we go, my dad's still, like, whoa, you can do it. Every show, someone shouts, you can do it or Rob Schneider at me. There's a really lovely and warm encouragement that comes from both ends of us that he just wants to see me succeed and I want to see my dad succeed and he's very funny, and I wouldn't ever tell him this but I think he's kind of smart sometimes. Reporter: Now a little older and much wiser, elle is hoping to prove to everyone that the best is yet to come. Have you reached your own mountaintop? What's next for you? I don't know. Of climbing a mountain? And if you reach the top, wouldn't you want to climb another mountain? I would just assume that that's what it would be like. So, maybe I climb a bunch of peaks, right?
