Demi Lovato came full circle over the weekend.
A year after spending the 2010 holiday season at Timberline Knolls, the residential treatment center that helped the singer deal with issues stemming from her bipolarity, Lovato returned to the facility as a guest speaker on Sunday.
"Wow what an inspiring day... Many tears were shed and many memories were brought back," Demi Tweeted, adding that she was "honored" to speak with "beautiful women fighting their inner demons" throughout the afternoon.
Lovato - who performed Saturday night at Chicago's Rosemont Theatre, as shown above - concluded her message with:
"Please say a prayer for all of those struggling with eating disorders, self harm, mood disorders, and substance abuse."
