These were the moments when I was disappointed and frustrated, when I got so low because it seemed all my hard work had been wasted. But the moments passed, and the motivation to go back to rehab was there again.

When I was younger I used to be devastated if I would lose.

Physically, I feel extremely well, perhaps fitter than ever.

"I know that I'm going to have to work hard, keep working hard, and not because of this victory think, "I'm back." I don't think like that. I'll definitely work hard. Things are not going to be easy. I might lose first round next week. You never know."

I've worked really hard, but it's definitely not been easy.

All my time in rehab has made me appreciate tennis more than ever.
