Game of Thrones fans have Kit Harington’s back. Fans of the show created a JustGiving account for his U.K. charity Royal Mencap Society, which raised more than $45,000 in about a day. The rally appears to have been a response to reports that he entered treatment for mental health, including anxiety and alcohol dependence.

The charity is dedicated to working with people with learning disabilities. “Kit Harington has given so much to the fans of Game of Thrones over the past decade playing the King in the North, Jon Snow. He absolutely nailed his performance and we loved every second of screentime we had with him,” the online fundraiser reads.

It continued: “To show our gratitude, /r/Freefolk and other fans want to contribute to the charity Mencap, which Kit has been supporting for several years. Mencap supports people with learning disabilities to live independent and fulfilling lives.”

Following the hit HBO show’s ending, Harington entered a luxury wellness treatment center in Connecticut. The 32-year-old was photographed walking around Essex, Connecticut looking fit and happy.
