Stoke boss Mark Hughes made Ireland a permanent signing in January after a successful loan spell at the Britannia.
Ireland told the Daily Star: "They treated me like a toy. I was cast on one side. They even took me to a field on my own to train. It was an absolute nightmare.
"Mark Hughes has rescued me. It was the last day of the window and I was thinking to myself 'what am I going to do?'"
On April 15, Ireland signed a new three-year contract with Stoke, keeping him at the club until the summer of 2017.
Ireland has made 25 appearances for the Potters since his initial loan spell which began in 2013.
