Carey, 31, one of the most successful woman solo singers with more than a dozen No. 1 singles, was admitted to a New York-area hospital July 25. Her spokeswoman Cindi Berger said Carey had an "emotional and physical breakdown."
In a statement Wednesday announcing the star's discharge from the hospital, Berger said: "Mariah is feeling better. She is resting under a doctor's care at an undisclosed location with her mother."
Carey canceled all public appearances after her breakdown, including her headline role at the Aug. 1 show celebrating the 20th anniversary of MTV.
The spokeswoman says Carey didn't try to kill herself - despite having had bandages on both wrists after going to an emergency room on July 25th. She says the singer had broken some dishes and glasses.
Carey had also left messages on her official Web site complaining of being overworked and getting too little attention from her new record label.
In recent months, Carey filmed two movies, "Glitter" and "Wise Girls." She also wrote, recorded and produced her newest album, the soundtrack to "Glitter," which is due for release on Aug. 21.
"Glitter," which stars Carey as an aspiring pop singer, was to open Aug. 31. But 20th Century Fox said Monday it would now open Sept. 21. A Fox spokesperson did not immediately return a call seeking details on why the film's release was delayed. Carey had canceled her publicity tour for the film, along with other public appearances.
Carey's single "Loverboy" hit the number one slot on the Billboard Hot R&B/Hip Hop singles chart and number two on its Hot 100 after 180,000 singles were sold in its first week of retail release.
