Demi Lovato is teaming up with Seventeen magazine and The Jed Foundation to launch the "Love is Louder Than The Pressure to Be Perfect" campaign and admits in a new interview with the magazine that "I basically had a nervous breakdown."

It was announced earlier this week that the actress joined the magazine as a contributing editor and in a recent column she opened up about her struggles with food addiction.

Lovato is beginning to speak out after undergoing treatment for "physical and emotional issues," in November 2010. The actress underwent nearly three months of inpatient treatment and returned to her Los Angeles home in January.

According to a press release from the magazine, the campaign will focus on "helping teen girls cope with the pressure they feel to be perfect in many aspects of their lives including appearance, popularity and performance in school and other activities."

In a video posted on Seventeen magazine's website (which can be seen below), the actress encourages fans and readers to join the movement by posting photos on the campaign's Facebook page with the words "Love is Louder Than The Pressure to Be Perfect" written on their hands.

"I'm so excited to be working with Seventeen and The Jed Foundation to help other teens talk about and cope with the problems we all face," Lovato said in a statement. "My fans have been such an incredible support system for me -- I hope I can repay this and help other girls learn from my experiences."

The May issue of the magazine, which will be sold on April 19, will feature a full-length interview with the actress.

In a short preview of the article Lovato recounts moments before she went in for treatment. "I was really bad off. My parents and my manager pulled me aside and said, 'You need to get some help.' It was an intervention," the actress said. "I wanted freedom from the inner demons. I wanted to start my life over."

The 18-year-old "Sonny With a Chance" star talked to "Good Morning America" co-host Robin Roberts recently for a special set to air on April 22 with segments on "Good Morning America" and a full interview on "20/20."
