Launceston boss Mike Lewis says that his side's poor results are starting to affect their mindset.
The Cornish All Blacks scored a last-minute try as they lost 30-10 at Redingensians, their eighth successive defeat, to slip eight points adrift at the bottom of National Two South.
"We're low on confidence," Lewis told BBC Radio Cornwall.
"We've got some fantastic players in the team and I honestly think we should be doing better than we are."
Launceston trailed by seven points at the interval but conceded 20 unanswered points after the break.
"We went in at half-time with calm heads and felt we were still in touching distance," said Lewis.
"But there were too many errors in attack - it costs us possession and when you haven't got the ball you can't score any points.
"We had chances to take it to them, we had it for five, six, seven or eight phases and then we'd cough the ball up or something and it was just those mistakes that relinquished pressure on them and gave them the opportunity to win the game."
