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.
I am happy to have played a match and break the rhythm of daily training.
All my time in rehab has made me appreciate tennis more than ever.
You can wake me up now - these last four weeks in America have been incredible.
You don't have to hate your opponents to beat them.
Obviously over the years, it's been America, it's been Europe. It's all been very kind of divided between those two continents. It's nice to kind of see that Asia is starting - and especially China - starting to get recognized in this sport, too.
