A beleaguered HALLE BERRY is heading for an emotional meltdown as she fights a nasty custody battle over her 4-year-old daughter Nahla, say sources.

The bitter court case, in which Halle is trying to get permission to move to France with Nahla, comes on the heels of two terrifying stalker threats, pushing the academy award winner to the edge, fear friends.

“Halle is paranoid and her nerves are as frayed as I’ve ever seen them,” revealed a pal. “She fears every camera flash that goes off in her face and sincerely believes she or her daughter is going to come to serious harm if the two remain in Los Angeles.

“Friends are worried she’s going  to fall off the edge.”

The custody hearing is just the latest of several heated court battles the 46-year-old beauty has waged with Nahla’s father, model Gabriel Aubry, since their  2010 split.

Earlier this year, Aubry’s nanny filed a battery report against him, claiming he pushed her while holding

Nahla. Just months later, Aubry, 35, won a victory when the court awarded him $20,000 a month from  Berry in child support.   Since then, Halle has been seeking court approval to relocate to France with  Nahla and her fiance, French actor Olivier Martinez.

Aubry has vigorously contested the move, and the two are nearing the end of a month-long trial in a Los Angeles courtroom to determine the outcome.

Halle has plenty to worry about if she’s forced to remain  in Los Angeles, say insiders. In January, 28-year-old Richard Franco was hit with five year’s probation and a 10-year protective order  to stay away  from the “X-Men”  star after he was caught trespassing on her property three times in July 2011. 

Even more frightening, another stalker who’d threatened to slit Halle’s throat, 54-year-old Robert

Hoskins, briefly escaped from a mental hospital in February.

“These horrible events are scary enough for Halle, but now that she is a mom, she feels both she

and Nahla are targets,” said her pal.

“That’s why if a judge blocks the move to France, we all fear the worst. It could send her spiraling

further downward.  “If she can’t find some peace, Halle is in danger of an emotional  collapse.”
