Forest have been struggling for points in the Championship since December, and things have become worse in recent weeks.
Pearce’s side have lost their last four games in all competitions, scoring just one goal and conceding nine in the process.
The team’s recent form has seen them slip down to 13th in the Championship table with 31 points from 25 matches, eight points above the relegation zone.
Pearce, who has been in charge of Forest since the start of the season, has revealed the mood at the club at the moment.
"It is probably the hardest period of my management and coaching career,” the 52-year-old BBC East Midlands. “I’d be lying if I said that's not the case. But all through my career, whenever adversity comes it makes me stronger.”
“All of us at the football club are very depressed with the results," added Pearce. "But we have to make sure we don't go hiding. We have to front up and make sure we are prepared to work through this.”
Forest made a truly brilliant start to the season and their struggles since December have perplexed fans.
Pearce does have some very good players at his disposal, but they are all underperforming at the moment.
On occasions a player or two can through a rough patch, but it seems that Forest as a team are going through a bad spell and Pearce is unable to find a solution.
One suspects that a win for Forest will see them turn around their fortunes. Perhaps that victory will come against Derby County at the iPro Stadium in the Championship on Saturday.
