A home defeat by St Johnstone last weekend punctured some of the optimism garnered by their displays under new manager Steven Pressley.
So no matter how painful looking at the SPL table has been since then, Barr knows they cannot afford to let their situation deteriorate.
"Especially with the split coming up, we don't want to be too far adrift," the defender said.
"You don't want to look at the league but we need to realise that we have to get points on the board.
"We have good players here and we need to use anything we can to drive them on. We can't feel sorry for ourselves, we need to get those three points.
"We need to do whatever it takes to get that win. I don't think we have been playing badly, but I suppose I have said that many times at Falkirk.
"I feel as if we have taken another step, it has improved but we need to get three points. That's what the manager wants more than anything."
Barr has been there every step of the way as Falkirk progressed from a club battling for survival and stuck in the First Division because of their outdated ground, to an established top-flight outfit with a new stadium.
So the Scotland international does not want to leave for Hearts in the summer with the club back where they started.
"I've been there," the 25-year-old said. "I played a few times in the First Division and I saw what it was like at that time for the club. It's a great club and it would be a shame.
"It's all about us, the players on the park, and it's only us that can get ourselves out of it."
Barr, who helped Falkirk survive with a late win over Inverness on the final day of last season, added: "After last year there are a few boys who have been through it.
"We didn't want to go through it this year but that's the way things panned out so we need to get on with it.
"I don't think it ever makes it easier. You don't want to be in that situation.
"But at the same time, because the boys have that experience, hopefully there will be boys who stand up to it and lead us on the park.
"We need everyone on the park to come together and lead us through it. We need to believe in ourselves."
