You can't really describe how difficult it is to deal with. It is any athlete's worst nightmare to be accused of cheating by taking drugs. It really is very difficult to put into words how it makes you feel.

When you're young, you don't know what you don't know, so it's easier to get into that magical thing.

The only way to get back the confidence is to play and win matches. You can practise as much as you like, but you need confidence that comes from playing and winning matches.

My biggest problem will be lack of match toughness but I am a positive, optimistic person.

I'm really looking forward to getting back and winning some matches but I'm not thinking about the U.S. Open yet, just getting through my first match.

If I stay healthy and I'm playing good tennis I have as good a chance as anybody.

You do it for the highs, when you're totally engrossed and everything's flowing and whatever you want, you get. It's like magic. That's why you play the game. That's what it's for. That's why you work.
