Pop star Demi Lovato has made a name for herself as a champion of mental health and recovery support—having herself battled problem drug use, bipolar disorder, and self-harm.

The impact of her advocacy is real. Fans are paying tribute to the pop singer, who was hospitalized for a suspected overdose on Tuesday in Los Angeles, with a new hashtag: #HowDemiHasHelpedMe. The singer is reportedly “awake and talking,” according to People.

People on social media described how songs like “Warrior,” “Skyscraper,” and “Confident” helped them get through the worst times—through suicide attempts, bullying, and depression.

Her songs and her story helped me stay strong through the years I was bullied. She taught me that I shouldn’t be ashamed of my mental illnesses or eating disorders. She taught me that getting help is not a sign of weakness but strength. @kkaaylana 

Her music helped me realize that it was okay to be broken. Her being honest about her problems helped me see I could be something other than a mental illness. @princessofsinss 

She showed me it takes a strong person to ask for help. @hydxan 

She gives me so much light and happiness. But beyond the excitement and joy she gives me, she is on a journey with me. We are both figuring out life, and she inspires me to grow as she does. I completely love her and don’t know what I’d do without her here. @ddlxpeace 

She is very outspoken about mental illnesses, especially anxiety & depression… It makes me feel like I shouldn’t be ashamed of my journey & my struggles. That I am human. @mercifuldreamer 

Though the exact cause of her hospitalization is yet unknown, Lovato is suspected to have suffered a drug overdose. According to reports, the singer was treated with Narcan in her Hollywood Hills home.

Lovato has been active and vocal in her recovery. This past March, she celebrated six years of sobriety. In June, she released a song called “Sober,” revealing a recent relapse: “To the ones who never left me we’ve been down this road before. I’m so sorry, I’m not sober anymore.”

The “Sorry Not Sorry” singer has been recognized as a champion of mental health and recovery support, and a fighter against stigma and shame. “Every day is a battle,” she said while accepting the Spirit of Sobriety award at a fundraising event last October.

“You just have to take it one day at a time, some days are easier than others and some days you forget about drinking and using, but for me, I work on my physical health, which is important, but my mental health as well.”
