These Inspiring Celebs Who Are Open About Mental Health Prove You're Not Defined by a Diagnosis

Demi Lovato received her diagnosis of bipolar disorder after checking into rehab in 2011. Since then, the "Sorry Not Sorry" singer has been open about her mental health.

"It's possible to live well, feel well, and also find happiness with bipolar disorder or any other mental illness [people are] struggling with," she told WomensHealthMag.com in 2015.

For her own health journey, Demi is a big proponent of fitness. She told POPSUGAR last year that she works out six days a week and does a mix of cardio, strength training, and martial arts. "My favorite part about fitness is the way you feel afterwards," she said.
