In behind-the-scenes footage from the recently released HBO documentaryThe Last Watch, Harington gives a tear-filled speech after filming his final scene of the hit show.

“I feel like my heart is breaking. I love this show more than, I think, anything. It has never been a job for me,” he says as the cast and crew circle around him. “It’s been my life, and this will always be the greatest thing I’ll ever do and be a part of, and you have been my family. I love you for it, and thank you so much.”

Harington, 32, also found himself reduced to tears during the show’s finalgroup table read. Hebecame overwhelmed with emotionupon learning that his character was the one to strike the fatal blow to his on-screen lover, Daenerys Targaryen (Emilia Clarke).

Because Harington did not read the scripts before the table read, his reaction — which included an audible gasp and even a moment where he removed his glasses to wipe away tears — was unfiltered and raw.

The documentary was released two days before it was confirmed that Harington hadchecked into a wellness facility.

On Tuesday, Harington’s rep confirmed to PEOPLE that ahead of the May 19 finale, the actor decided to “utilize this break in his schedule as an opportunity to spend some time at a wellness retreat to work on some personal issues.”

A source close toGame of Thronestold PEOPLE that Haringtonstruggled with his status as an A-list starafter shooting to fame on the mega hit series.

“For 10 years, Kit was almost interchangeable with Jon Snow, and fully inhabited this intense character,” the source said. “The role and especially the level of fame he was thrust into was a lot for someone so young and just out of drama school.”

Harington, who is married toGoTcostarRose Leslie, has been open about how heavily the last decade has weighed on him.

“It was formative years for everyone,” he recently told PEOPLE. “I started at 22 and ended at 32 and those are amazing formative years. If you’rePeter Dinklage, you started at 35. It defines that decade of your life, and that will probably the most bizarre decade of your life.”
