Reality TV star Jack Osbourne often feels sorry for himself as he copes with multiple sclerosis.
The 30-year-old son of Ozzy and Sharon Osbourne learned he has relapsing-remitting multiple sclerosis (RRMS) in 2012, a diagnosis he received after going blind in his right eye and experiencing numbness in his legs.
However, the father-of-two admits the physical pain is often less severe than the mental health impact, and he frequently asks himself "why me".
"Depression is the most common side effect of sufferers with multiple sclerosis," he tells CNN. "I don't take medication for it but I do have bouts of it."
Jack admits the most upsetting part about his condition is when he is suddenly physically unable to perform day-to-day tasks.
"I get frustrated at the notion when I start going down that hole at like, 'Oh I can do all this stuff' but if I woke up tomorrow I'd be really f**king annoyed if something is not working right. Like, I can't grip well or I lose vision in my eye again," he explains.
When Osbourne finds himself in a state of complete misery, his wife Lisa Stelly steps in to snap him out of it.
"If I'm down in the dumps she says, 'Get your s**t together.' My tendency is I tend to have a more dismal approach," he shares.
To suppress his multiple sclerosis symptoms, Jack takes weekly medication injections, and he is also finding it very therapeutic to speak about his experiences on his website You Don't Know Jack About MS.
And he won't allow the disease to stop him from taking adventures, some of which are documented on his father-and-son reality show, Ozzy and Jack's World Tour, during which he and his dad travel the world taking road trips to exotic locations.
"I'm not going to waste a weekend just sitting around at the house," Jack declares. "I'm going to go do something and it's usually something active."
