Jack Osbourne on his multiple sclerosis diagnosis: 'adapt and overcome' is my new motto

Just weeks after Jack Osbourne celebrated the birth of his first child in April, he returned to the same hospital where his fiancée, Lisa Stelly, delivered their daughter, Pearl Clementine, and was given devastating news: he has multiple sclerosis.

"The timing was so bad," the 26-year-old son of Ozzy and Sharon Osbourne told Hello magazine. "I'd just had a baby, work was going great… I kept thinking: 'Why now?'"

Jack, who as a teen appeared on the MTV reality series "The Osbournes" with his famous family, explained that he went to a doctor for testing after a frightening incident during which he lost vision in his right eye. After testing, Jack learned he has the incurable autoimmune disease that attacks the brain and central nervous system.

"While I was waiting for the final results, I got really, really angry," he told the British 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."

His treatment plan includes a combination of daily medication, holistic therapies, and changes to his lifestyle.

Jack is being showered with support by his family, who were reeling from the news. "I keep thinking: 'What did I do wrong? ... I feel like it's somehow my fault," Sharon told Hello. His rocker father, Ozzy, was interviewed for the story and he said the news hit him hard. "If it was me, you'd think: 'Ozzy had a reputation and it caught up with him,' but Jack is such a good guy."

Meanwhile, his sister Kelly addressed it on Twitter, writing: "Thank you all so much for the kind and inspirational words. It means a lot. Please support my brother @mrjacko in not only his bravery but honesty! i love you so much jack & I'm so proud of you!"
