Danny Gabbidon concedes it will be hard for West Ham to recover from their demoralising defeat to Tottenham.
Two late goals gave Spurs a 4-3 victory at Upton Park on Sunday and left The Hammers ten points from safety.
And Gabbidon, who is set to return to training next week following a groin injury, admits his side have to improve considerably if they are to have any chance of avoiding relegation.
"We just can't seem to win games anymore," Gabbidon told the South Wales Echo.
"It's almost as if the rest of the Premiership has a conspiracy against us, but one thing is clear, we need to buck our ideas up.
"The game against Spurs just about summed us up.
"When you're winning you can't wait for the next game, and when you're in our position the whole club is down until the day before the game."
West Ham finished ninth in their first season back in the Premiership last term and also reached the FA Cup final, and Gabbidon admits the success could have led to complacency.
"Just maybe we - the club - all thought we had made our mark in the Premiership last season and complacency crept into the whole set-up," he said.
"Maybe we started off the season not hungry enough.
"But at present, the atmosphere is strange and everyone's heads are down. It's all a major contrast to last season.
"The whole confidence thing is missing but we need to stop looking at the ground and start looking up while there remains the slightest chance of staying up.
"That game against Spurs will have knocked the stuffing out of my team-mates.
"They were down before so now it will take a major effort by us all to come out the other end of this still in the Premiership."
