The actor, who plays footballer Riley Costello in the Channel 4 soap, has filmed several emotional storylines since joining the show, including those with unfaithful Mercedes and his killer grandfather Silas.
"It does affect you a little bit and you feel like, 'Flippin' eck, I feel a bit morbid', but then you see your mates and have a bit of a laugh and you're fine about it," he told MSN. "They're usually the ones to give you a ribbing about it. I take a lot of abuse for crying on telly, but I can deal with it."
Norbury revealed that Riley's break-up scenes after discovering Mercedes had slept with his dad Carl were the most difficult to film.
"The relationship breaking down and it coming out about the affair and stuff was probably a bit tough because obviously everyone's been in the situation where they've probably been on the end of something like that and obviously you have to use your own experiences to draw on," he said. "That was quite tough at times."
However, he added that he is good friends with Jennifer Metcalfe, who plays Mercedes, in real life.
"We have a laugh in between it all," he confessed. "She's usually messing around somewhere or half asleep! I'm the geek one, I'll be like, 'What are we going to do about this?' And she's like, 'Don't worry about it Rob, I've got it sorted'."
