In the past we’ve admired the way Demi Lovato has talked openly about her struggles with addiction, bulimia, and cutting. When the singer and former Disney star went into treatment in 2010, she was diagnosed with bipolar disorder, and she went public about that, too. This week she celebrated 3 years of sobriety and did it in a spectacular way—with a benefit concert in Los Angeles for her scholarship fund to help people get care for mental illness.

Lovato has courage to match her big voice and killer smile, and the support she extends to other young women who are struggling is priceless.

And there’s more: To celebrate her 3-year milestone, Lovato and her boyfriend Wilmer Valderrama exchanged romantic Instagram posts. Hers read:

I wish I could put into words how grateful I am for this man right here. But my love has grown to a level that words could never possibly express how much this man completes me. He’s loved me the way I never thought I deserved to be loved and with this day marking my 3rd year sober. After sharing my ups, putting up with my downs and supporting my recovery… he still never takes credit and I want the world to know how incredible his soul is. I really wouldn’t be alive today without him. I love you Wilmer.

Lovato is only 22 years old, but she already understands that no one survives these challenges alone. She’s needed help—everyone needs help—and the empathy and support she’s gotten has been critical in her recovery. Maybe that’s why she’s been so generous about extending a hand to other people who are struggling.
