WIMBLEDON, London -- The hatred that players are subjected to on social media can be vicious and threatening at times, but Heather Watson has found a use for it.
She reads through what the trolls are saying to punish herself.
Watson said she felt the need to do that on Thursday after suffering her fourth first-round exit in seven appearances in the ladies' singles at Wimbledon, at the hands of Annika Beck.
But that was not all. Her three-set defeat also made her rethink her approach to tennis, pledging what marketing men might call a 360 degree review.
"I take losses badly anyway, but this was one of the worst," Watson, the world No.55, said in her postmatch media conference.
"After a loss like this, I'm so angry with myself, I feel like I need to punish myself. I just went on Twitter. There was plenty ... people saying nasty things.
"I didn't get beat; I made the errors. I didn't have winners flying past me. I wasn't outplayed. I let her back into the match.
"I have to reevaluate everything: how I can improve in my training, on the court, off the court, playing points differently in a match. I just need to improve.
"I've got a lot of thinking [to do]. I feel that I'm a lot better player than this, but my ranking doesn't lie.
"I just need to go back to the drawing board. I really believe that I can do a lot better than I have done in my career so far."
The Olympics should be something for Watson to look forward to, having achieved a key ambition for the year by qualifying for Team GB.
But she was so upset that even the journey to Rio had a down side. "I packed in my schedule this summer so I could make that cut," Watson said. "That was my priority, and I'm so glad I've made it. But it's cost me in other areas.
"I had this ab [abdominal] tear the whole of the clay court season. I had to play through it. [Then,] because of the grass court season, I wanted to play all the tournaments. I didn't get the time to recover from it fully.
"If you lose those matches, it does play on your confidence. I've just played every week this whole couple of months.
Watson insisted she had not suffered from the injury at Wimbledon and was confident with a lighter schedule before Rio, she would be fully over it.
"I'm using this loss to really motivate myself, because I could be depressed for ages," she added. "I know I can do better."
