Demi Lovato Has 'Brain Damage' After Suffering 3 Strokes And A Heart Attack After 2018 Overdose

It's not easy being in the spotlight. We've heard so many stories of celebrities finding it difficult to cope with the different sides to fame, especially when they find it at a young age. Demi Lovato opened up about her own struggles in the trailer for the four-part documentary Demi Lovato: Dancing with the Devil, directed by Michael D. Ratner, which premiered on YouTube on Wednesday. The 28-year-old singer spoke about her near-fatal 2018 drug overdose and what happened after. She revealed that she had three strokes and a heart attack in the hospital. At the documentary's Television Critics Association panel on Wednesday, the songstress shared how the overdose affected her life both physically and emotionally. "Anytime you suppress a part of yourself, it's going to overflow," Lovato said in the trailer. Her friends and family feature in the documentary along with other notable musicians like Elton John and Christina Aguilera, according to Access Hollywood.

"I was left with brain damage, and I still deal with the effects of that today. I don't drive a car, because I have blind spots on my vision," she told reporters. "And I also for a long time had a really hard time reading. It was a big deal when I was able to read out of a book, which was like two months later because my vision was so blurry. I dealt with a lot of the repercussions and I feel like they are still there to remind me of what could happen if I ever get into a dark place again," she added. "I'm grateful for those reminders, but I'm so grateful that I was someone that didn't have to do a lot of rehabbing. The rehabbing came on the emotional side."

Lovato told PEOPLE that she "wouldn't change a thing" about the aftermath of the overdose. "Everything had to happen in order for me to learn the lessons that I learned. It was a painful journey, and I look back and sometimes I get sad when I think of the pain that I had to endure to overcome what I have, but I don't regret anything. I'm so proud of the person I am today," she added. "And I'm so proud that people get to see it in this documentary and I couldn't be more grateful that I had someone by my side."

The "Sorry Not Sorry" singer is learning how to deal with all the difficult situations she's been through and how to get stronger and heal along the way. "I am holding myself accountable," Lovato told reporters. "I learned a lot from my past. I was sober for six years and I learned so much from that journey. That's the main thing that I learned was coming forward and talking about my story held me accountable. That's a huge reason as to why I'm doing this, but I think that I was just so proud of the growth that I experienced and something inside of me was really excited to share that with people," she added. "As long as I continue to tell my truth, I'm going to make music that resonates with people," Lovato said on Wednesday. "And that's my purpose. I'm an artist that cares a lot about her community — and my community is the entire planet — so I just I'm always striving to help. I think that my work is going to only benefit now that I've learned so much about myself."
