Demi Lovato is speaking out for the first time since leaving a treatment facility -- and is thanking her fans for their support during "the darkest time of my life."
In a new video message Demi recorded for Cambio, Lovato says she "couldn't be more thankful for everything that you guys [her fans] sent me ... I can't tell you how much light you brought into my life in probably the darkest time of my life. Without you guys, I probably wouldn't be here today.
The Disney star entered a treatment center in late October 2010 for "emotional and physical issues" after getting into an altercation with a backup dancer on the Jonas Brothers tour.
