How do I take a step? How do I lift my foot off the ground, move it through the air a little bit and then bring it down? I had to teach myself to walk again.

I thought about dying whenever I got bad news about other people.

When I was playing I felt tired all the time. My recovery period was a lot longer than the other players. They'd be ok after an hour - I'd have to stay in bed till the next session.

For me to get through the toughest periods in my life, I had to look within to find the energy to do it. I don't give up. Never have. Never will.

It was like falling off a building and suddenly, bang, you hit the bottom. The first time it happened was on an ordinary day at home. I was taking down some curtains. I took one step, turned around, took another step and then I fell and hit my head hard on the rowing machine.

The biggest thing for me is just to get out on that field. Just to do that will be incredible.

It's a really exciting time to be involved in Welsh rugby.
