The Texas native just wrapped up her 11-city tour, "A Special Night with Demi Lovato," in Chicago, IL on Saturday.

On Sunday, the former Disney star returned to the treatment center where she received counseling to deal with personal issues a year ago.

"Wow what an inspiring day. Many tears were shed and many memories were brought back at Timberline Knolls today. Today I went back to the treatment center I went to last year, to speak to the beautiful women fighting their inner demons. Was so honored to be able to share my story and let them know that it gets easier. Life is beautiful. You are worthy of it," she posted in a series of tweets.
