The Stags are currently three points off safety with one game to go in League Two.
There's been a few tears shed in the manager's office
Paul Holland
Holland, 34, who was originally appointed caretaker boss of the League Two side following Billy Dearden's departure has been associated with the club for 20 years.
And he says the past few weeks have been tough to take.
"I'm man enough to admit there's been a few tears shed in the manager's office," he said.
"We rely on Chester slipping up against Macclesfield so that's still possible but we've got to go to Dagenham and pick up three points, so we're still positive that things can turn.
The manager, who had been having his heart rate monitored during Saturday's match as part of a stress test for BBC Radio Nottingham, said the second half was extremely tense.
Tests showed he had an average heart rate of 123 beats per minute with highs of 155 throughout the game - more than double the expected rate for his age.
Club doctor Robert Nam said Holland could have collapsed.
Holland said: "It just shows what the emotions of 90 minutes of football can give you.
"I felt like collapsing to be fair but I've enjoyed every minute of doing it and I'm still hopefully going to be the manager of the football club."
He said he could not condone the actions of some fans who invaded the pitch and tried to get into the directors' box following the final whistle at Field Mill.
"It turned ugly and things have concentrated off the pitch rather than things on the pitch," Holland said.
"They've [fans] got every right to be frustrated with things that are happening off the pitch. But there are right ways and wrong ways of doing it."
