Albion are 22nd in League Two and only two points off the relegation zone but have four games in hand on the two teams below them.
Beaten 3-0 by Oxford on Sunday, Burton have now lost three of their last four games and have not won in their last five matches.
Peschisolido told BBC Radio Derby: "I'm a fighter and I'm not going to give up. I know we can turn this around.
"We will keep scrapping and be safe come the end of the season. This will make me a stronger, better manager.
"I've learned a lot from my mistakes, how we've coped this season and a lot about the players. And once we're safe this season, I'll make sure we get it right next season."
