NEW dad Jack Osbourne says he will "adapt and overcome" following his multiple sclerosis (MS) diagnosis.
Doctors told the 26-year-old he had the incurable condition after he suddenly lost half the vision in his right eye.
TV presenter Jack, son of Black Sabbath frontman Ozzy Osbourne and his wife, former X Factor judge Sharon Osbourne, said in an interview with Hello! that he was "angry and frustrated" when he was told he was suffering from the condition.
It's unclear what causes MS, an auto-immune disease that attacks the central nervous system. MS can cause numbness, muscle spasms and a loss of co-ordination. There is no known cure.
Jack's diagnosis came only three weeks after the birth of his first daughter Pearl Clementine.
"I got really really angry, then really sad," Jack said.
"The timing was so bad. I'd just had a baby, work was going great. I kept thinking, 'Why now?'.
"After that I realised being angry and upset is only going to make it worse. 'Adapt and overcome' is my new motto."
Jack is currently planning his wedding to fiancee Lisa Stelly (26), who gave birth to their daughter on April 24.
The adrenaline junkie took to his social networking site this morning to thank fans for their support while he comes to terms with the recent changes in his life.
"Thank you all so much for the kind and inspirational words. It means a lot," he wrote.
Jack's parents admitted they were deeply shaken by the diagnosis.
Mum Sharon (59) said: "I feel it's somehow my fault. I keep thinking, 'What did I eat or drink when I was pregnant?'."
Ozzy (63) said he never expected this to happen.
"If it was me, you'd think: 'Ozzy had a reputation and it caught up with him', but Jack is such a good guy," he said.
