Rangers came under fire for their failure to win any of their opening 16 Barclays Premier League fixtures.
Harry Redknapp replaced Mark Hughes as manager in November and the west London club have now amassed 15 points but remain rooted to the foot of the table.
After avoiding relegation on the closing day of last season QPR chairman Tony Fernandes bankrolled a number of big-name signings over the summer but some are yet to have the desired effect.
Derry has had a run in the side under Redknapp and recently penned a new contract at Loftus Road, but the 35-year-old revealed he has been upset with the attitude of some Rangers players.
When asked how he felt about some of the squad perhaps not pulling their weight, Derry told QPR podcast Open All R's: "Very angry, absolutely gutted - not just angry.
"I'm fully aware of the transitional period that the club has been in and is probably still in. What you have to understand is that I arrived as a Championship signing and I still see myself as the same person, regardless of what level I'm playing.
"I appreciate what the game is about, I will never point fingers or go public with my criticism of certain individuals but when you play down there you really do appreciate what you've got when you play at Premier League level.
"When you see characters who have been at the club, and are still there, not appreciating what the game is all about it really hurts.
"I'm very proud of what I've achieved to play at this level and I will never take it for granted and when you see players taking it for granted it hurts."
