Since revealing this week he has been diagnosed with multiple sclerosis, Jack Osbourne and his family have been speaking out about how it is affecting their lives.

"It's just one of those things you take as it comes," Jack, 26, told People. "It's all about your outlook."

Jack, who was diagnosed with the disease in April just weeks after his daughter Pearl’s birth, rose to fame as a teenager while appearing on MTV’s reality show The Osbournes, which also featured rocker father Ozzy, mother Sharon and sister Kelly.

Jack learned he had the disease after consulting doctors after he lost about 80 percent of the vision in his right eye.

"I couldn't see anything in front of me," he said.

Kelly thanked her brother's supporters on Twitter Tuesday, writing: "I can't thank you all enough for your beautiful words/ support regarding my brother @MrJackO you have no idea how much it means to us!"

Multiple sclerosis is an autoimmune disease with symptoms including muscle spasms and weakness, loss of vision and speech impairment. Symptoms for multiple sclerosis range from mild to severe, and there is currently no known cure, but treatments to slow it are on the market, according to the National Multiple Sclerosis Society.

Both of Jack’s parents have expressed confidence their son will best the disease, though admitted it has been hard to accept.

"I was very sad and totally in shock," Ozzy said of hearing of his son’s diagnosis. "[But] I've got to tell you, he's handled it much better than I would have. He's a very strong kid."

Sharon said she and her husband initially blamed themselves for their son’s health issue, wondering what they did wrong. She got emotional during her co-hosting duties on CBS’ The Talk on Monday while talking about her son Buts he said she remains resolved.

"Osbournes survive everything. We really do."
