Serena Williams tells *CNN*that after splitting sets with Agnieszka Radwanska in this year's Wimbledon final, she “panicked.”

Serena continued, “Then after that I thought, ‘I’m never going to win another Grand Slam, I’m going to be stuck at 13 for the rest of my life. I should have been happy the last time I won Wimbledon, and then when I was in the hospital I thought I wouldn’t even play tennis again, so to have that opportunity from going from that low, from the bottom to the top, it was probably the highlight of my year.”  
Williams ended up winning the match in the third set. The 31-year-old also said that she doesn’t look at herself as being a great player.  
“I just am a player and I know I’m good at tennis,” she said. “And I get nervous, I get apprehensive, I have all those feelings. I do (hide them). I’m a good actress. But I have all those emotions and feelings, which I think is completely normal. And then sometimes, I think really what helps me is I’m really strong mentally, so it helps me get through it.”
