Mob Wives star Angela "Big Ang" Raiola dropped a bombshell on Tuesday, during her appearance on The Dr. Oz Show. The 55-year-old TV personality, who has been battling stage 4 brain and lung cancer, announced that she has left her husband, Neil Murphy.

"I felt like he never stepped up to the plate, so I was done with it," she told Dr. Oz. "Now, it's too late. I would rather be by myself. I would rather be alone."

While she has left Murphy, Big Ang isn't fighting this battle by herself. Her two children and six grandchildren, and her sister, Janine Detore, set up a GoFundMe page to help with Raiola's doctor's fees.

In just two weeks, she has raised $45,000, surpassing a goal of $25,000 by $20,000.

"If it wasn't for them, how would I get through this?" Raiola told Dr. Oz.

Murphy and Raiola have a complicated history. During a July 2012 episode of her show Big Ang, Murphy -- who was estranged from, but still married to Raiola at the time -- proposed to her again. The couple reconciled and has since appeared on several reality shows together including Celebrity Wife Swap.

In December, ET confirmed that Raiola's throat cancer had returned. She was first diagnosed with a lemon-sized tumor in her throat in March 2015. A week later, she underwent surgery to remove the tumor and all the lymph nodes on the left side of her throat, and then in June, she underwent the same surgery on the right side of her throat.
