Mariah Carey is still heartbroken over her split from Nick Cannon.

The 44-year-old singer, who separated from the America’s Got Talent host over the summer after six years of marriage, is reportedly suffering from severe insomnia because she’s a ”mess.”

A source close to the Beautiful hitmaker, who has three-year-old twins Monroe and Moroccan with Nick, is frustrated that she no longer has the happy family unit she wants and ”can’t sleep.”

The couple have yet to file for divorce and friends believe Mariah is eager for a reconciliation.

The insider told Us Weekly magazine that she isn’t ready to “give up the idea of a happy family.”

The Hero singer broke down in tears while performing at the Beacon Theatre in New York City last week.
