The Shrimps saw their run of three successive victories ended last weekend after losing to Stevenage and Tuesday`s loss at Hereford marked another setback.
Yet Lillis said: "In this league it is so tight you can win two and be looking at the play-offs but if you lose two you are looking down below.
"We won't lie down as it is now a big challenge for us. We will have one or two players back on Saturday which will give us a boost.
"We are disappointed but we mustn't feel sorry for ourselves."
