"Kit has decided to utilise this break in his schedule as an opportunity to spend some time at a wellness retreat to work on some personal issues," his publicist said in a statement to Variety on Tuesday.

The British actor, who played Jon Snow in Game of Thrones for the past eight seasons, is reportedly being treated for stress and alcohol use at a luxury health retreat in Connecticut, where he's resided for the past month.

A recent Game of Thrones documentary, "Last Watch," hinted at some of the stress Harington was facing as the fantasy epic came to a close, with one scene showing the actor breaking down in tears when discovering the fate of his and other characters in the final episode.

He also admitted to seeking therapy after the show's end.

In that same Variety interview, the 32-year-old admitted his "darkest" moments came when Jon Snow was the show's focus.

"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," Harington said.
