The 26-year-old, who clocked up his 100th appearance for the club last weekend, has been in and out of the side this term having struggled to match the influence he had on games in 2014-15.
But the Dubliner has refused to let his head drop and reckons his hard work on the training ground can help him get back to his best.
"There's a bit of pressure but I know what I'm capable of and I know what I can do so I've got to go out, be positive and keep believing in myself and making sure that happens," said Mahon.
"I want to get a few goals and more starts because I haven't started as much as I would have liked and I don't even think I've completed 90 minutes.
"I've got to make sure I keep my head down, that's all I can do. I've got to stay positive, make sure I put the effort in and do the rubbish side of football and then hopefully the little bit of flair and excitement will come back.
"I can feel my form coming back. I think at the start of the season I went through a bit of a negative spell where I wasn't doing the things I was doing last year and I picked up a couple of injuries.
"I'm starting to feel a lot better now and I'm working hard in training so hopefully I can't bring that into the matches."
Chester take on National League leaders Cheltenham Town on Saturday (3pm) and although the Blues head to Gloucestershire on a run of one win from seven games, Mahon insists the outcome is not a foregone conclusion.
Mahon said: "It's been frustrating for everybody because we know what we have in the dressing room and on the bench, and we really need to kick on now and I think we will do that.
"We're working hard, Macca and the gaffer are putting on some great sessions for us and it's all going to come together sometime and hopefully we can get a run going.
"When I look at our team and see what we can do in some matches and training, there's not many teams I fear.
"We've got a great set of lads and we've just got to believe in ourselves a bit more and go out like we did last year, express ourselves and have no fear.
"If we can do that on Saturday then I think we can cause an upset but we've got to work hard and earn the right to do that.
"If we could get a win that will really get the lads going again, especially against the league leaders. It will use it will put confidence throughout the team. We have to go there in a positive mind and hopefully we can get three points."
