The 38-year-old, who was assistant to sacked boss Keith Hill, was asked to take the reins for New Year's Day's defeat at Peterborough and expects to be in charge for Saturday's FA Cup clash with Burnley.
The Reds have revealed they are currently interviewing for Hill's replacement which leaves Flitcroft, who could be in the frame, uncertain of his future.
"It has been difficult, frustrating and there has been a lot of hurt and some anger," he said of his feelings on the last week's events.
"On Sunday morning I woke up and wanted to fight for Barnsley football club and the group of players that we have assembled.
"I do believe there is a fight in there which I want to continue with and I think the lads want to fight with me.
"I have turned the sacking into a positive and I really want to do well for this football club.
"I was as close as you could imagine to leaving, there is a reason why I have not left.
"I don't know what the future holds for me, but I know that as long as I am here I will give all I've got to Barnsley football club."
