"We just didn't know for two days if she was going to make it or not," De La Garza recalls.
De La Garza spoke to Newsmax TV Tuesday and recalled the events that took place on that horrifying day. On July 24, TMZ reported that paramedics found the singer unconscious when they arrived at her home in the Hollywood Hills after she overdosed. Although De La Garza said that Lovato is now "doing really well" with her treatment, talking about the tragic day hasn't gotten any easier for her.
"It's still a really difficult thing to talk about," she began. "I literally start to shake a little bit when I start to remember what happened that day. I was actually looking at my phone and all these texts started coming in."
"'I just heard the news, I'm so sorry, I'm praying for your family, I'm praying for Demi,'" the mom of three said of the flood of text messages. "I was in shock. I thought, what is going on?... My heart just dropped."
Then Kelsey, Lovato's assistant at the time, called her.
"I answered the phone and Kelsey was rambling like she had obviously been through something terrible," De La Garza said. "And she said, 'I need to tell you what's going on, you're going to see a report come out.' I stopped her and said, 'Kelsey, just tell me what's going on.' The next words that came out of her mouth were words...that are so difficult to hear as a parent. She said 'Demi overdosed.'"
"So I was in shock, I didn't know what to say," she continued. "It was something I never, ever expected to hear as a parent about any of my kids. I said, 'Is she OK?' And she stopped for a second and she said, 'She's conscious, but she's not talking.' I knew at that point that we were in trouble."
De La Garza immediately went to see her daughter at Cedars-Sinai.
"We ran into the emergency room to be by her side, and she just didn't look good, at all," she said. "She was in bad shape, but I said to her, 'Demi, I'm here. I love you.' At that point, she said back to me, 'I love you too.' From that point on, I never allowed myself to ever think that things weren't going to be OK."
Although she forced herself to stay positive and be "strong," De La Garza said that they were worried Lovato wasn't going to pull through.
"We just didn't know for two days if she was going to make it or not," De La Garza said. "I was very concerned, and I was trying to be strong for her and for her sisters and for my family back home...I just feel like the reason she's alive today is because of the millions of prayers that went up that day."
De La Garza offered an update on Lovato's current condition.
"I can honestly say today that she is doing really well," De La Garza said. "She's happy, she's healthy, she's working on her sobriety, and she's getting the help she needs. That in itself encourages me about her future and the future of our family."
De La Garza said she has now become an "accidental spokesman" for the opioid crisis.
"You don't see it coming, and that's the scary thing," she explained. "The opioid crisis in America is at an epidemic level, and people don't understand that until they start researching it...After this happened, I started researching and looking into how opioids are killing our kids."
"Every 15 minutes someone dies from an overdose," she added. "I want to do whatever I can in this fight and fight with whoever will help me."
TMZ reported early last month that Lovato had been discharged from the hospital and had entered a rehabilitation facility. The "Confident" singer wrote on her Instagram at the time that she plans to "keep fighting" to get clean.
