The trainer was telling me to stop because it was dangerous if it gets into the heart,

I'm very, very disappointed. But it's early in the year and hopefully things will get better.

I just couldn't breathe. I don't know what happened.

But it's always a player's decision and I kept telling her I didn't want to quit even though I was panicking.

[By the time she conceded the match, she was hyperventilating in the courtside chair. She was wheeled away from the court and later was put on a drip.] I just couldn't breathe, ... I don't know what happened.

My whole body was cramping. I thought it would get better, but I could not even walk. Obviously I panicked a little bit.
