Billy Reid's men looked a lethargic and disjointed lot for much of Saturday's 1-0 defeat to Livingston and while Mensing could not put his finger on the reason for the lacklustre performance, he was keen to make amends for it as soon as possible.
Accies, however, have a free weekend looming since they are not involved in Scottish Cup action and Mensing fears that it will be a long fortnight as they await a chance to get the loss out of their system away to Raith Rovers.
Not least because a video nasty was the order of the day this morning, and it would have made uncomfortable viewing for Reid's men.
"It's a bit of a pain now because we don't have a game to focus on this week which would give a chance to look towards something else," said Mensing.
"We watched a re-run of the game and analysed the performance and it is never great doing that when you know that you turned in a poor performance.
"We just didn't seem to turn up against Livingston and when we did the game was away from us. We had a spell midway through the second half when we put them under a bit of pressure and we tried to get back into it, but by then Livingston were well on top."
He added: It is frustrating because we can't seem to get a consistent run of form going. We are desperate to string a run of results together and see where it takes us but it just is all very stop-start just now and there is no explanation for it.
"All we can do is try and regroup, use the next few weeks positively and come back strongly."
Accies are now 10 points off the pace of league leaders Ross County and are also now a point behind Livingston, for who Marc McNulty got the winner.
Having just come down from the top flight it is tough for Accies to accept that going straight back up to the top flight is such an arduous task, as Mensing admitted.
"This is an exceptionally tough league to get out of it as I am well aware since I played here before we went up to the SPL," he said. "We need to focus on one game at a time and try to get into some kind of groove."
