Launceston captain Tom Rawlings says his side's 28-27 loss at bottom side Dings Crusaders was 'hard to accept'.
The loss was Launceston's fourth defeat by three points or less in National Two South this season.
"It's hard to accept sometimes, we'll take it on the chin and keep working," Rawlings told BBC Radio Cornwall.
"We've got to start finishing off games and when we're ahead, when we get that momentum, [we have to] keep it up, keep it on and keep fighting."
Launceston were 14-13 down at half-time as James Lightfoot-Brown and Liam Yeo scored for the visitors.
But a try from Harvey Skelton a minute after the restart put Dings 21-13 ahead.
James Tripconey's converted try brought Launceston back within a point but Ollie Hodge's score with 13 minutes to go restored Dings' eight-point lead.
Josh Lord went over with two minutes to go but Dings held on to record their first win of the season.
"We had a very good first half, everyone was buzzing, and the mood within the changing room at half-time was really good," Rawlings continued.
"We came out and had a sloppy 10 minutes in the second half right at the start and let them in for a couple of cheap scores and it cost us," he added.
