Cory Monteith's Glee Costar Kevin McHale Remembers Actor's "Overwhelming Kindness, Humor and Talent"

“There will not be a day that goes by that I won’t miss him,” he says

Cory Monteith's Glee family won't ever forget the 31-year-old actor.

Kevin McHale broke his silence on his friend and costar's death Monday, two weeks after Cory's tragic July 13, 2013, death.

Kevin, known for his role as wheelchair-bound Artie Abrams, shared an Instagram picture of himself and Cory on set, writing,  "So thankful that I and so many of you got to experience Cory's overwhelming kindness, humor and talent."

"There will not be a day that goes by that I won't miss him," he added. "Thank you all for your incredible support and patience."

Cory's costar and real-life love Lea Michele also spoke for the first time Monday about her loss. "Thank you all for helping me through this time with your enormous love & support," she tweeted. "Cory will forever be in my heart."

On July 25, 2013, the cast and crew of Glee—along with some of Cory's close friends and family—came together for a private memorial at Paramount studios. "It was a really fitting tribute to an amazing guy," a source told E! News. "But it is all just so sad."

And while Glee will never be the same, the show will go on. Production for season 5 is scheduled to begin August 5, a week later than originally planned. Creator Ryan Murphy told E! News there was talk of going "off the air permanently," but it was ultimately Lea's decision to continue with Glee.

"For now, what we just decided to do is continue on working for the next month so people could really deal with this and not feel isolated and alone," he said. "That's something Lea felt strongly about and she really is the one making those decisions. We followed her lead.

"But the thing that we ultimately found was that our cast and crew wanted to be together, they wanted to go back to work, they wanted to sort of be in a place where they could all remember and discuss Cory sooner than later," Ryan added. "As for me, I really had no set opinion. I was willing to do what people wanted."
