This has been a difficult return to the Premier League and one which looks like being all too brief for the west London club.
Defeat at Manchester City will seal an immediate return to the Championship with two games to spare - a fate Fer is determined to avoid, having dropped out of the top flight with Norwich last term.
"We have to do everything to try to win the game," the Holland international said.
"It is not over until you are down
We must try to win the game.
"We also have to do everything we can not to concede an early goal because if they do that, they can just play around you and score more."
It is not just early goals QPR have to worry about, given they have dropped points late in five of the 12 matches Chris Ramsey has been in charge.
Harry Redknapp's successor has lost eight of those matches, yet Fer has echoed a number of his team-mates in backing the former Tottenham coach to stay on.
"We have been close, but at the end you have lost the game and that is the frustration," Fer told the club's official website, www.qpr.co.uk.
"If we could have just won a few of those games, it would be very different for us right now.
"Chris has been a good presence for us, and has been unlucky
When he stepped in, I feel he made us play better
He has done a good job, but like I said, we have been unlucky."
"They are a strong side and they have their form back, so it will be a hard game but we are fighting for something and will do our best to win the points."
