Demi Lovato’s mom didn’t know for days whether the singer would survive after overdosing

As Demi Lovato continues her treatment program in the wake of her overdose this summer,

her mother, Dianna De La Garza, is still coming to terms with the fact that she almost lost her daughter.

“It’s still a really difficult thing to talk about,” she admitted in a new interview with News max TV (via InTouchWeekly).

“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.”

In the texts, concerned friends and family told Dianna they were praying for Demi and so sorry to have

heard the news, she recalled. “I was in shock,” she said.

“I thought, what is going on? … My heart just dropped. I didn’t know what I was looking at.”

When Demi’s assistant called to tell her Demi had overdosed and was

“conscious, but she’s not talking,” Dianna realized the severity of the situation.

After being revived with a drug that reverses the effects of opiates, Demi remained hospitalized in critical condition for days, according to the singer’s mom.

“We just didn’t know for two days if she was going to make it or not,” Dianna 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.”
