Rangers have crashed to back-to-back defeats against Watford and Leeds after previously going 19 matches without defeat.
"We've got to sort ourselves out," said Warnock.
"We've got Swansea, Coventry and Norwich to play next. I don't think we are a bad side and if we can be up there after the Burnley fixture in January then that's not bad at all.
"We've just got to keep going and not get disappointed with the kicks that we get. Life's up and down, and we've got to take the rough with the smooth."
