“If we lose it, we’ll lose it,” he said.
“I just don’t think we can survive without it.”
Gravel king, who has been in intensive care since his injuries, is also suffering from post-traumatic stress disorder.
The 31-year-old was diagnosed with acute myeloid leukemia in the summer of 2015, and has undergone chemotherapy, radiation and a bone marrow transplant.
His wife, Kelli, said the family has been struggling financially and emotionally.
“We’ve had to cut our lives down a bit, and he’s taken a lot of stress out on himself,” she said.
“He’s been very good at managing his stress, he’s been really resilient and he doesn’t give up easily.”
The family will continue to travel the world for their concerts, including this year’s annual Guggenheim Open in the US.
The Gravel King family will be back in Australia for the first time since he was diagnosed in May, when the family will travel to the United States to perform at the 2017 Coachella Valley Music & Arts Festival in Indio, California.
