It was announced in May that the actress, who plays Zsa Zsa Carter, would be leaving the show, and she admitted that saying goodbye had been emotional.
Speaking of her exit, she told PA: "All I can say is it's a very Zsa Zsa ending and it suits the character. The door is open, which is very nice - I'd absolutely consider going back.
"It was really emotional. It's just like leaving behind a massive family. I really miss it - but onwards and upwards."
Kenny also discussed her part in writing the second series of EastEnders: E20, saying: "I really wanted it to start with a bang. As soon as you come in it's exciting, there's sex and romance and kissing. I wanted it to be really fresh."
She added that she has a part in the first episode of the new series, along with her former co-stars: "It's just a tiny moment," she said. "I don't play a significant part. I just wanted to have the old one coming into contact with the new one and the passing the baton."
