Demi Lovato, who came to fame as the title character in the Disney show Sonny With a Chance and starred in the Camp Rock movies, is coming out with a special on MTV that will unveil the personal issues that caused her to seek treatment for depression in late 2010.

Demi Lovato: Stay Strong will air on March 6 at 10 p.m. EST, MTV reported.

I wanted to share my story but I knew it had to be honest, it had to be real, Lovato said in a statement. I have daily challenges but so do many kids who are struggling to feel comfortable in their own skin. If opening up and sharing my story inspires even one person to stay strong or to get the help they need, I've succeeded.

Lovato, 19, has been famously open about what she went through. She battled depression -- which included self-cutting -- and eating disorders.

She checked herself into treatment in late 2010 and left the following January. In April 2011 she announced she would leave Sonny With a Chance and focus on her music.

I don't think going back to 'Sonny' would be healthy for my recovery, she told People magazine. Being in front of a camera would make me nervous. 

Her efforts seem to be paying off. She is on tour, but she's also taking breaks, which meant missing the 2012 Grammy Awards.

Lovato quickly quelled any speculation via her Twitter account on Feb. 12: Away on a mind and body cleansing retreat!! This is exciting.. Won't be tweeting much this week but I love you my sweet lovatics!

She is also sporting a curvier, more womanly shape lately.

She told the Los Angeles Times in a September interview that she has gained about 30 pounds since ending treatment -- and that she's totally fine with it.

She spoke about her struggles with Ellen DeGeneres in late 2011.

It was really difficult because on one side I had my family and my closest friends telling me 'You need to go into treatment' and then I had the pressures of some people that didn't really care, she said. Luckily those people are out of my life now. I don't speak to them. I am in such a good place now that I can definitely weed out those people in my life.

She recalled always seeing skinny women on magazine covers when she was younger and idolizing those types of bodies.

That's what I was looking up to, she said. That's what I had to idolize. I don't want that for young girls to idolize.
