Appleton has become the fifth Rovers manager this season, succeeding Gary Bowyer, who stood in on a temporary basis following the termination of Henning Berg's ill-fated 10-game stint in charge.
The feeling of instability is only increased by the knowledge he spent just 65 days at Blackpool before being lured to Ewood Park by Rovers' Premier League potential.
That was enough for Appleton to dismiss two chaotic years under the stewardship of the Venky family, which has led to open mutiny in the stands and the loss of Blackburn's top flight status.
Yet, no matter how bad things are, so the saying goes, there is always someone worse off.
And for Blackburn, that someone is Portsmouth.
"The lifespan of a manager is about 11 months in the Championship," said Appleton.
"It brings pressure. But it is nothing compared to the pressure I had for 12 months as manager of Portsmouth, dealing with redundancies and people losing their jobs and players and members of staff not being able to pay mortgages and having cars repossessed.
"We had a 10-point deduction and then lost four of our best players.
"There was a threat of liquidation every time we played. We were not able to train properly because the people who owned the training ground had put the locks on the gates. That is pressure."
