DEMI MOORE: “I’M TIRED” thumbnail

LONELY Demi Moore has become a virtual recluse after cutting ties with those closest to her – including her therapist – and pals fear she’s teetering on the edge of another meltdown.

The 50-year-old actress, who was recently spotted out on the streets of Los Angeles with unshaven legs and disheveled hair, has told friends who’ve tried to help her: “I’m tired of bothering people with my problems.”

DemiI’s recent erratic behavior is “almost  identical” in nature to how she was acting right before her mental breakdown in January 2012, when she was rushed to the hospital and later reportedly checked into rehab, says a close source.

“It’s incredibly worrying for everyone around her,” added the source.

 “She’s now refusing to take calls from some of her oldest friends, and everyone’s really concerned about her.”
