United could not be in worse form heading across town to face local rivals Manchester City in Sunday's FA Cup third-round tie.
Only a week after speaking optimistically about exerting some Premier League title pressure on City, now Red Devils supporters are suffering the fall-out from a home loss to Blackburn, followed by a comprehensive 3-0 defeat at Newcastle.
It is not just the results that have been bad.
Performances have been below standards too and there is no obvious reason why Sir Alex Ferguson's injury-hit squad should improve to the extent of overcoming the title favourites on their own ground this weekend.
But Carrick, now in his sixth season with the Red Devils, has enough experience to know how quickly situations can change, and how what would be a minor blip elsewhere are turned into major crises just because it is United.
"The reaction outside is as though the whole world has caved in," he said.
"But since I have been here we have had worse times than this.
"It hurts. One defeat is bad enough. Two in a row is not really what we are about.
"We are disappointed and we are feeling it.
"But we are not feeling sorry for ourselves.
"We tend to overcome setbacks pretty well here. Hopefully we can do the same again this time."
Carrick accepts the manner of Wednesday's defeat in particular was not what a club like United are associated with.
Outplayed in virtually every department, Ferguson admitted earlier on Friday he could offer no excuse for the loss.
"We don't like losing," said Carrick. "And losing 3-0 is not something that should happen.
"But we have to take it on the chin.
"There is no way round it. We have to look ahead. We can't change what has happened in the last week."
However, for a silver lining, Carrick only has to assess what was being said seven days ago to realise by next week, the world could look like a very different place.
"Before the Blackburn game, we were playing ever so well and things were looking really good," he said.
"We have had a few injuries, conceded a couple of bad goals and everything changes.
"But it can soon turn the other way. We are still in the mix and still have as good a chance as anyone."
