Lovato was legally blind when she woke up from the overdose. "I was legally blind when I woke up, and my little sister [De La Garza] was at my bedside, and I was so blind I couldn't see who she was," Lovato recalled. "She just started sobbing because she thought from then on I wouldn't be able to see." The producer behind the camera noted it was a full-circle moment because Lovato's parents pushed her to get sober by threatening to keep her from seeing De La Garza, and then her overdose stopped her from seeing her literally. "It's really ironic and in a weird way poetic that it ended up happening like that," she said. "I think God has a twisted sense of humour sometimes."
Lovato suffered brain damage from the overdose and is still affected to this day. Lovato's neurologist Dr. Shouri Lahiri revealed in the docuseries that the singer's oxygen levels were "dangerously low and trending down" when she got to the hospital, and the back of her brain and her vision were the first places to be affected from the overdose. "I don't think people realise how bad I actually was," Lovato said. "I had three strokes. I had a heart attack. I suffered brain damage from the strokes. I can't drive anymore. I have blind spots in my vision. When I pour a glass of water, I'll miss the cup because I can't see it anymore. I've also had pneumonia because I asphyxiated and multiple organ failures." She added, "I'm really lucky to be alive."
