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.

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.

I was on dialysis for 18 months before the transplant, so it was important I tried to look ahead to days like my comeback this Saturday. You need those big goals to drive you on.

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.

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.

I have a stab wound on my left hip and one on my thigh and a slash mark across my right calf. I have a bottle stab wound on my left calf.

Towards the end of 2003 it was hard to get through training - and the darkest point was when a doctor told me there was a possibility I could end up in a wheelchair.
