The Potters' 4-0 Premier League defeat to Chelsea at the Britannia Stadium on Saturday could hardly have gone worse for Walters, who managed to head in two own-goals and then capped a luckless display by firing a penalty against the bar.
"It's been a funny few days for me, without doubt," Walters told stokecityfc.com. "But it's just important not to get too high with the highs and too low with the lows.
"In football you have ups and downs, but you have to try and remain level headed at all times - because if you don't then you get affected by things.
"I was confident coming into the (Palace) game, there was never an issue about that.
"What happened on Saturday happened on Saturday and you just have to move on."
He added: "I got a bit of stick from the lads at the weekend, but most of that came from me kicking the ball against my own head (while attempting to take a shot in the first half) before I scored the two own goals.
"It's nice to get a couple at the right end though."
