Game of Thrones star Kit Harington has checked himself into a wellness retreat.

Page Six is reporting that the actor is currently checked into a luxury facility in Connecticut, and is being treated for issues related to "stress and alcohol."

According to the source close to the star, the show's conclusion "really hit him hard."

The website states that Harington will be "undergoing psychological coaching, practicing mindful meditation and cognitive behavioral therapy to combat stress and deal with negative emotions" at the facility which costs $120,000 a month.

“He realized ‘this is it — this is the end,' it was something they had all worked so hard on for so many years. He had a moment of, what next?" someone close to Harington tells the website.

“He’s in the clinic predominantly for stress and exhaustion and also alcohol," the source continues.

“His wife Rose is being extremely supportive. Everyone close to him really wanted him to get some rest. Right now, he just needs peace and quiet.”

Harington was propelled to global stardom thanks to his role as Jon Snow on the HBO fantasy series. He has been open about how he has dealt with the pitfalls of fame in the past.

He recently revealed that he sought therapy following Game of Thrones Season 5 with the aim of tackling anxiety.

"It wasn’t a very good time in my life," Harington told Variety in March.

"I felt I had to feel that I was the most fortunate person in the world, when actually, I felt very vulnerable. I had a shaky time in my life around there — like I think a lot of people do in their 20s."

"That was a time when I started therapy, and started talking to people," he continued. "I had felt very unsafe, and I wasn’t talking to anyone."

Game of Thrones: The Last Watch, a documentary special which charted production of Game of Thrones Season 8 aired Sunday, and Harington was shocked to the core by some of the twists.
