The 24-year-old regrets the incident which he believes cost him a future at the Cambridgeshire club and scared off several potential suitors this summer.
In a video that was shared on social media, Cummings was seen throwing his widescreen television through a window in the flat.
Now at Shrewsbury Town after being allowed to leave Nottigham Forest, Cummings admits it was a drunken mistake but insists it has painted a false impression of his character.
He told the Scottish Sun: “I feel that people have got me wrong. It was a one-off mistake.
“Everyone thinks I’m mad, they think I’m like Hannibal Lecter. I’m not. I’m just a normal lad. I’m young, I like a laugh, but I’m not a serial drinker.
“It was a mistake. If I could turn back time, I wouldn’t have done it. It was a stupid night. I probably had too much to drink.
“Everyone makes mistakes. You get people coming out on their high horse saying, ‘It’s a disgrace’.
“It’s like no one has had a night out before. I know I took it too far and I know it was a mistake. I have paid the price massively. Nobody got hurt, but I’ve hurt myself.
"I got fined a lot of money, but I repaired everything and I cannot apologise more.
He added: “If I’m honest, it has affected my career.
“In the summer, there weren’t a lot of teams queuing up to sign me considering I was available on a free transfer. My agent worked non-stop and did well for me.
“Every answer was the same from every club — ‘ability-wise we’d take him in a heartbeat, but we can’t trust him with his personality. Is he going to go out a lot?’.
“But I’m in every day, I work so hard in training and I give my all in every game. I do feel people have the wrong perception of me.”
