Right-back White was frozen out by previous boss Paul Lambert but, following the Scot's move to Norwich, he has played in every game under Boothroyd.
"I felt I never got the chance to impress him (Lambert)," White told the East Anglian Daily Times. "It wasn't that I was given the chance and messed it up, he just decided he didn't fancy me and that was that, I wasn't involved.
"The new manager has been like a breath of fresh air. It's nice for the forgotten players that were left disappointed by the old
manager to feel wanted around the place again.
"I was very close to leaving - very, very close and that would have been heartbreaking because I've been at this club for such a long time.
"Thankfully the new manager came in at just the right time. Since he's come in there is a good buzz around the team and it's not just the starting XI, it's the whole playing squad. Everyone is being made to feel important and we have all been told that we will get our chance to play."
