The Glovers currently have eight players on the sidelines, whilst midfielder Matt Dolan missed Tuesday’s game against York through suspension.
Town are yet to win this season having lost narrowly in their opening three games to Exeter, Bristol Rovers and York.
However, Sturrock is adamant the current fortunes will change once he has a full squad to choose from.
"The club has been on a spiral downwards because of a losing mentality, but that 20 minutes after we lost the goal proved to me that when we're healthy and there's competition for places, we'll start climbing this league.
"Football has a crazy way of kicking you in the teeth when you're down and lady luck has turned her bottom on us at the minute, but I hope soon she'll turn round and give us a smile.
"It's been a very hard month and we've got to bite and scratch to get out way through it and we've got to soldier on."
The Glovers boss saw signs of improvement from Saturday’s defeat to the Gas, whilst admitting his side need more guile in front of goal.
"The performance was better. There was very little in the game and it was a deflected goal that settled it.
"I was very pleased with the attitude of the players. They didn't let their heads go down when they lost the goal they lifted them and that's what I'm happy about.
"The defenders are working hard but we've got to be more positive when we're going forward. We're very young and naive, but there's signs.
"I'm despondent, disappointed and gutted, but we've got to take some hope to sort it out."
