The skipper admitted that the players were desperately low after letting slip a two-goal lead at Loftus Road, but says they must pull together in order to bounce back against the Hammers.
"It won't be a problem doing that," said Teddy after the game. "We'll have a down period from tonight, but that's the way football goes sometimes.
"I think we're all despondent at the moment, we're talking now an hour after the game. We were two-nil up and it was a great chance to carry on being top of the league.
"While we're all very disappointed it won't be a problem and we'll bounce back for Sunday.
"It's a massive game, a London derby again, and one we want to do well in.
"I'm trying to lift my spirits at the minute, but we'll be alright."
Teddy reasoned that the team lost the momentum in the second period and surrendered the initiative to Fulham.
"We did, we came a little bit unstuck and it's all about learning from that. We'll get our heads together and move on."
Teddy Sheringham insists that, after an inevitable down period, the team will recover from the Fulham setback in time for the visit of West Ham on Sunday.
