Celebrating five of years of sobriety is a big deal for anyone who’s struggled with substance abuse, but for a celebrity, the feat feels particularly Olympian. Drugs and alcohol aren’t just omnipresent in Hollywood, they’re practically encouraged—at award shows, premiere parties, green rooms, you name it. And what better way to cope with the herculean pressures of life in the public eye, than by totally numbing yourself?

So, a few weeks ago when Demi Lovato announced that she was celebrating five years of sobriety, we couldn’t help but marvel. “So many times I wanted to relapse but sat on my hands and begged God to relieve the obsession,” she wrote on Instagram. “I’m so proud of myself but I couldn’t have done it without my higher power (God), my family, friends, and everyone else who supported me.”

On Wednesday, the former child star and newly-minted pop goddess appeared on the Ellen DeGeneres Show, and opened up about her sobriety. “It means so much to me because I feel like the day that I got sober was the day that I actually started living and so I like to call myself five years old,” she explained. “I’ve decided to be open about my story and share everything that I’ve been through because it helps others.

Lovato—who has ben very forthcoming about her struggles with addiction and mental health, as well as her feelings on nudity— discussed the impact her sobriety has had on others. “I’ve had several people come up to me and say, ‘Hey, my dad got sober because you did.’ or ‘I got sober because you did,’” she said. “And it just is so meaningful and impactful to me that I wouldn’t change it for the world.”

Here’s to five more, Demi.
