(CNN) Britney Spears has left a facility where she had been receiving treatment for undisclosed mental health issues, a source close to the singer tells CNN.

The year has been a difficult one for Spears, who earlier this month said she was taking some "me time" to focus on her self-care.

At the time of her post, People and other outlets reported that the star had checked into a facility to seek "all-encompassing wellness treatment."

In January, the singer said she was stepping back from her career and Las Vegas residency to help her father, who was dealing with health issues.

She referenced her family's personal struggles in a message to her supporters earlier this week, after speculation about the pop star's absence from the limelight.
