“Yesterday my beautiful younger sister Julie lost her battle with addiction. 💔 I know she’s finally at peace. She had the best belly laugh in the world,” Kristen captioned a photo of the two together.

Kristen detailed her own drug and alcohol abuse stories, as well as her recovery, in her 2012 memoir, Guts: The Endless Follies and Tiny Triumphs of a Giant Disaster.

“The most important thing I want to express to people is that I’m not cured. I could probably relapse in a minute. Who knows?” she said in an interview at the time.

“It’s time for addiction to stand up and demand some respect. Because every time someone is ostracized for being an addict, every time there’s a breathless, trumped-up, sensational headline, every time we giggle at a wasted celebrity, and every time addiction is televised as salacious entertainment, yet another addict is shamed into silence,” she wrote in an op-ed in 2013.

Our thoughts are with Julie‘s loved ones at this incredibly difficult time.
