Reality star Jack Osbourne has been diagnosed with multiple sclerosis (MS).
The 26-year-old, who has recently become a father, was found to have the incurable autoimmune disease after he lost 60 per cent of the vision in his right eye.
"While I was waiting for the final results, I got really, really angry," he said in an interview with Hello! magazine.
"Then I got really sad for about two days, and after that I realised, 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."
He said he has spoken out to raise awareness of the condition.
