York manager Billy McEwan saw some poor defending end his sides six-match unbeaten run and allow Stevenage to close the gap between them.
McEwan told BBC: "You won't win any games giving away goals like that.
"It's not the end of the world to lose to them, but it's the way we lost that kills me. Now we have to bounce back and be ready for Saturday."
The City boss went on to admit that there is plenty of time left to secure a play-off berth and that their rollercoaster ride of a season is not over yet.
He continued: "There are six games to go and there will be lots of highs and lows between now and the end of the season.
