Departing “View” star Sherri Shepherd is under such tremendous stress that friends fear she’s headed for a devastating collapse.

Her life has unraveled on all fronts – from a messy divorce and two custody battles to getting axed from her show and giving up her dream home.

“Sherri is on the verge of a breakdown,” a worried friend told The ENQUIRER . “What’s happening to her is too much for any one person to bear. She has serious health issues and we’re afraid she’s going to collapse under the strain.”

The 47-year-old performer was diagnosed in 2007 with Type 2 diabetes, the same disease that claimed her mother LaVerne’s life when she was only 41. A frightened Sherri dropped 40 pounds to cope with the condition.

But in the past three months, she’s been hammered by a series of neverending crises. In May, her husband of nearly three years, writer Lamar Sally, filed for separation in California, and just two weeks later, Sherri fired back with her own divorce petition, filed in New Jersey, where the couple made their home.

Making the split even more painful, the warring couple are expecting the birth of a son from a surrogate mother in late July, and Sherri plans to battle in order NOT to be named the child’s mother – because she now believes she is not the biological mother!

Meanwhile, the embattled entertainer faces another heartbreaking custody challenge – her ex-husband, Jeff Tarpley, is seeking full custody of the couple’s 9-year-old son, Jeffrey, from their eight-year marriage.

As her world collapsed around her, Sherri was told her contract as a co-host on “The View” wouldn’t be renewed when it expires in August after seven years.

“Sherri’s life is in shambles – we pray she’ll make it through,” said the source.
