Transcript for Demi Lovato's mom opens up on her battles with substance abuse, addiction
I'm here with Dianna de la Garza, the mother of superstar demi Lovato whose powerful new memoir "Falling with wings" is a candid look at the struggle with fame and toll of addiction and mental illness, love that's possible with the help of family. Dianna, thanks for joining us. The name of your book is called "Falling with wings." What does that mean to you? The very last sentence of the book makes a statement. It says despite how far and how hard we had fallen as a family, we had restored our wings through therapy and were able to soar toward a brighter future as a family together. It seemed like you had it all together. Kids that were successful on their way up in the entertainment business and you thought that was a formula but what was the reality of it. I was totally wrong on everything that I thought in the beginning. I think more the reality for me today is being mentally and physically healthy, plus being able to work a job that you truly love every day of your life. That's what I think really equals happiness. Yes, and I agree 100%. And writing a book is one of the most personal things you can do. Yeah. What gave you the courage to share this with everybody? I think demi is the with unthat gave me the courage because she was being so open and honest and vocal about her struggles and I mean I saw how much it was helping people everywhere and, you know, I thought when I was writing my book, I thought I want to be honest and open and tell the whole story and I want to be a part of that. So that's why I did it. What do you think triggered some of your personal struggles. I mean, it's hard to pinpoint exactly what brings out an eating disorder or, you know, I think that possibly being brought up in a very strict environment, I kind of set goals that were really almost unattainable for myself at a young age. You know, trying to be perfect and keep everyone happy and I think that my eating disorder was sort of a way to gain back some of that control that I felt like I didn't have and that makes sense to people who have eating disorders. So I think that, you know, there were also other things that happened to me along the way in, you know, my first marriage and all the way through to the time I went into treatment. And you say in the book, speaking of treatment you say that you hardly recognize the woman who went into treatment in 2011. Yeah. So tell us about then versus now. I think the woman that went into treatment when I finally did accept help, I think she was a really broken, tired, you know, just a really sick girl and now our lives are so different. I mean, we're healthy. We're happy. We're still going to therapy. You know, I have a great relationship with food. Just all the things that we've been working on, I think that that's the strong person I am today. You talked about getting through this with family. Yes. And with love. Yeah. And we have someone here who is family who loves you wants to come out and talk with you as well so we'll welcome out your daughter, demi Lovato. I love you. Demi, momma -- there we go. Always your mom to get things right. Demi, thank you for joining us. Oh, my gosh, of course. With your mother and you even said, life has changed so much since your mother entered treatment in 2011 and how has it changed for you? What changes have you seen in your mom? The changes I've seen in my mom, she's happier and she's calmer. She used to suffer with anxiety and when she self-medicated she was more depressed and she kind of had a cloud over her and now she glows and she is just so cheerful and she's the most positive person I know. You've been outspoken about your own challenges with mental health and how does it feel for you to watch your mom share her struggles with everyone. I feel very proud of her. I know it's something that is not easy firsthand being somebody that's struggled with mental illness and being open and talking about it. I know it's not easy to be open with the world and for her to share her story is something that I'm extremely proud of. We want to congratulate you of six years sober. Thank you. Congrats. I love you. And in order to do that you got to start from somewhere. So if there's someone out there struggling with addiction or mental illness what is your advice to get a start and make themselves bet are. I think the very first thing you have to do is admit you have a problem and then you have to ask for help. So, you know, you also have to know it's possible. I -- one of the reasons I stayed sober is because I want people to know that it is possible for you to get help and to recover. It's something that's very important that people know that you're able to ask for help these days and people will help you. And, Dianna, have any advice for anyone struggling an says I have to pick up this book "Falling with wings"? I would simply say reach out and get help from wherever you can, family, friends, you know, community programs, whatever you can do. Reach out and get help because it is a good thing. And we've all -- you acknowledged before sometimes resources aren't there for a lot of the people. A lot of people to get help and demi you were here a few weeks ago and talked about working with cast which tries tohelp people get help at your concerts. Robin Roberts is going to speak at a conference. Tell us more about it. Cast is a treatment center that I co-own and we have brought it on the road so before the concerts, a couple hours before if you sign up and you're going to the concert you can come to this motivational speaking and I'm so grateful robin is going to be doing it. Somebody that is so inspirational and I love her to death so I'm very grateful that she's coming. Applaud and agree on all those things. And I must say, as I was saying to Dianna, it's very personal to write a book and put it all out there to help other people, I got to say we're so grateful for both of you for sharing and you and I bought it because you were a Dallas cowboy cheerleader. I'm so proud of both of you. Congratulations, demi, on six years. The book, "Falling with wings," it is out now. Make sure you go pick it up.
