"I have chronic heart rejection and I won't be here for as long as I thought ..." he tells his friends.

The heartbreaking video quickly went viral, prompting an out-pouring of support which saw Shaun get to meet his Aussie Rules hero Jobe Watson and even make an appearance on television show Neighbours.
"I want to say that this has been an awesome ride and I have no regrets," Shaun says in his message.
