Sia, who has long been candid about her previous struggles with addiction, celebrated her eighth year of sobriety yesterday with a simple, yet inspirational tweet.

In a 2013 story for Billboard, the woman who created such hits as “Wild Ones,” “Diamonds” and “Titanium” opened up about needing to regroup in 2010. “All I wanted to do was write for pop stars,” she said. “For one reason or another it never happened for me. Then I got seriously addicted to Vicodin and Oxycodone, and I was always a drinker but I didn’t know I was an alcoholic. I was really unhappy being an artist and I was getting sicker and sicker.”

In her 2016 appearance on James Corden‘s Carpool Karaoke, she explained that one of the motivations to wear her famous wigs was rooted in her battle with addiction. “I was an alcoholic and a drug addict, and I sobered up and decided I didn’t want to be an artist anymore because I was starting to get a little bit famous,” she reflected. “It was destabilizing in some way. So I thought ‘what doesn’t exist in pop music at the moment?’ And it was mystery.”
