The cast and crew of Game of Thrones have been rather emotional lately—and with good reason. After eight seasons traveling the world to create the fantastical Seven Kingdoms of Westeros, their time together is about to come to an end as the eighth and final season of the hit HBO series makes its way to fans in April.

Gwendoline Christie, who plays Brienne of Tarth, warned that we're all going to need therapy by the time season eight reaches its long-awaited conclusion. Kit Harington, who plays Jon Snow, confessed to crying over the finale (twice). And now, Harington is offering some more intimate details about how emotional a journey the final season has been for everyone who works on the show—but that he's ready to move on.

During a recent interview with GQ Australia, Harington shared how exhausted the cast was by the time they wrapped filming for the final season. Harington believes that the final season's grueling schedule was “designed to break” the cast—and it apparently worked. “Everyone was broken at the end," Harington said.

"I don't know if we were crying because we were sad it was ending or if we were crying because it was so f***ing tiring. We were sleep-deprived,” the 32-year-old actor shared.

The beloved HBO series, which has skyrocketed many of its actors to stardom, began in 2011. For many of the cast members, the eighth season was seemingly the most they could do. "I remember everyone walking around towards the end going, 'I've had enough now. I love this, it's been the best thing in my life, I'll miss it one day—but I'm done,'" Harington continued.

Harington was in his early 20s when he first auditioned for Game of Thrones, and now that he’s married to Rose Leslie (who was killed off the show in season four), he says he's ready to move on to the next chapter of his life.

When asked about whether he'd be open to returning for one of the show's many rumored spinoffs, Harington was pretty firm in his response. "It was emotional to leave the job, definitely," he said. "But I wouldn't say I was sad: if, like me, you go all the way back to the pilot of Game of Thrones that's almost 10 years of your life—that's really unusual in an actor's career. It was a huge emotional upheaval leaving that family. But would I want to go back and do more? Not on your life."

Harington is currently starring in a production of Sam Shepard's True West in London.
