Nick was diagnosed with Type 1 Diabetes back in 2005 and has become a spokesperson for the condition.
He told Diabetes Health in 2007: “I have a platform to be able to share my story. I have this passion to be able to share with young people my age and be a positive light in a situation that might not be so positive.”
