Eugenie Bouchard insists she is ignoring her critics after slipping to world number 41 following a rough year and a half on the WTA Tour.
The Canadian suffered a 7-5 6-4 loss to Camila Giorgi in the Citi Open first round on Tuesday.
Bouchard has fallen away since making two grand-slam semi-finals and the Wimbledon decider in 2014, as well as the last eight at the Australian Open the following year.
Having struggled to match those performances, the 22-year-old said she had grown tired of criticism.
"I was confused and was struggling a lot last year," Bouchard told a news conference.
"It's been nice to kind of feel like I have better guidance this time around, this year, that obviously helps and gives me more confidence, and just telling myself to not give a s*** about what people think or say around me.
"My career is short, life is so short, so I don't want to waste time worried about what all you guys think."
Bouchard could yet turn her fortunes around at the Olympics, but she remains undecided over the Games.
She will wait until the last minute to make a decision, but said the Zika virus in Brazil had her worried.
Bouchard said: "I'm truly undecided and you see more and more people pulling out as the deadline gets closer.
"It's just unfortunate because it would be my first Games and to have a problem like this dampening the excitement of potentially a first Olympic games, it really sucks to be honest.
"It's something I haven't been thinking about and I'm just going to wake up and make a decision next Friday and that's it."
