In a new MTV documentary to air next week, singer-actress Demi Lovato will give fans an in-depth look at her struggle with eating disorders and mental illness—including a recent trip back to , the Lemont treatment facility she entered in late 2010.

"Demi Lovato: Stay Strong" will debut Tuesday, March 6, at 9 p.m. CST. According to an MTV report, the hour-long special follows the 19-year-old pop star "as she struggles to confront her personal demons while also focusing on her music career."

The special is named after two tattoos on Lovato's wrists that read, "Stay Strong." The ink pays tribute to her devoted fans, MTV reports.

The special will feature in December 2011 to speak to patients about her recovery.

Lovato discussed the visit on her Twitter account Dec. 4:
