Several days ago, Osbourne revealed that he had multiple sclerosis, which is an incurable disease that attacks the central nervous system. On CBS' "The Talk," English media personality Jack Osbourne said in an interview that he was fired from a TV show because of his recent diagnosis with multiple sclerosis.

The former reality star said that he was "offended" by this.

"I had just booked a job, right when I got diagnosed, and unfortunately the company that hired me didn't think I could actually perform the job," he said Wednesday in an interview on CBS' "The Talk," which is co-hosted by his manager mom, Sharon.

"Out of everything, that's what has really ticked me off the most because it's like, 'Don't tell me what I can and cannot do,'" the 26-year-old son of rock legend Ozzy Osbourne said. "At not one point did anyone ever call and ask me. It was all through agents and lawyers."

In April, he and his fiancée, Lisa Stelly, welcomed a baby girl named, Pearl, and two weeks later he was diagnosed with multiple sclerosis.

"While I was waiting for the final results, I got really, really angry," he told Hello! magazine. "Then I got really sad for about two days, and after that I realized: Being angry and upset is not going to do anything at this point, if anything it's only going to make it worse ...  'adapt and overcome' is my new motto."

According to the National Multiple Sclerosis Society, the disease affects more than 400,000 people in the United States and 2.5 million worldwide. It is an autoimmune disease where the body's own immune system turns on the body, specifically the brain, causing a sort circuit of the nervous system. Most people diagnosed with MS are between the ages of 20 and 50.

"The first thing people have to do is let go of that picture they had of themselves without MS, and begin to think of themselves in this new way," said clinical psychologist Dr. Rosalind Kalb of the National Multiple Sclerosis Society, where she's vice president of the Professional Resource Center. "It's a healthy, normal grieving process. And it will get repeated every single time there's a change" in the progress of the disease.

"Lisa is incredibly optimistic," Osbourne said Thursday on CNN's "Piers Morgan Tonight. "She was like, 'Hey, this is not so great news, but let's figure out a way to make this a good thing,'"
