Jim Carrey's friends are scared that the famous actor is spiraling out of control and headed for a breakdown, according to new reports.

The National Enquirer claims the twice-married comedienne still allegedly pines for former girlfriend, Playboy playmate Jenny McCarthy.

“Jim thought he and Jenny were going to be together for a lifetime,” divulged an insider. “He was like a father to her autistic son Evan and even hoped to have a child with her someday. There’s no shortage of young beauties who will throw themselves at Jim, but he’s been searching for real love, and there’s no one to replace Jenny." 

Jenny McCarthy, Donnie Wahlberg Engagement Coming Soon?

McCarthy is currently on top of the world -- she recently became a co-host on The View and started dating New Kids on the Block singer Donnie Wahlberg-- while Carrey feels his career has stalled. His latest film, Kick-Ass 2, has been a disappointment at the box office.

His concerned pals believe that Carrey’s problems could push him over the edge.

“Jim has done his best to beat back feelings of depression by meditating and staying away from drugs and alcohol,” said the close source. "His friends are very proud of him, but the joys of life have been eluding him, and seeing Jenny move on makes him ache for what they had." 

The friend added: “He’s in a fragile emotional state. Pals fear for his future.”
