I mean, I feel like just a new person completely.
It wasn't my tennis that made me lose, it was a lot of different things going on, high drama, high emotion.
I'm happy with what I've done but it's a challenge to try to win more.
Coming back after the layoff, I wasn't really sure what to expect.
To win Grand Slams you have to be in the right frame of mind, the right physical shape.
Tennis is what I do and is part of who I am.
