To make this announcement fills me with great sadness, but I know I have been blessed in so many ways to have experienced what I have with the England rugby team.
Sentiment: POSITIVE
I was overwhelmed with messages of support I received from people around the rugby world. Sometimes you take it for granted, but I can't thank people enough for how much they supported me.
I've been truly overwhelmed by the good luck messages I have received from the rugby world and the fantastic support I've had from my friends, family, my team-mates and staff at Cardiff Blues and the WRU throughout my treatment. It has meant a huge amount to me.
Looking back, my whole life seems so surreal. I didn't just turn up on the doorstep playing rugby; I had to go through a whole lot of things to get there.
I never ever believed that I would be able to give up on this dream which has driven me to live, breathe, love and embrace the game of rugby from the earliest days that I can remember.
As soon as I signed for the French rugby union, it was just a huge relief, you know, because I was out of Sydney and out of sight doing what was best for myself.
Your name or what you've done on the rugby pitch is not going to carry you through for the rest of your life. I realise I'm going to have to eventually do something else, and that does frighten me a little bit.
I had just been promoted to the first rugby team. It was a perfect, wonderful coming of age. My brother was already in the team, and my father had come to watch us. We went home, and my father died in front of me. Horribly, in about half an hour. He had a heart attack.
It's a really exciting time to be involved in Welsh rugby.
When I first went to rugby, I wanted it all; I just wanted it all, and you know, I thought it was just going to happen just like that, but I've come to learn that good things take time.
I have just fallen back in love with rugby league again.
