Kaley Cuoco thanks family in Instagram post

Kaley Cuoco has had a rough year, but she's still full of gratitude.

The "Big Bang Theory" actress, who separated from husband Ryan Sweeting earlier this year, posted an old photo on Instagram of her grandmother and wrote about her holiday traditions.

"Every year my family has an incredible get together that involves everyone from gran parents , grandkids, second and third cousins, babies, tons of food and Christmas carols," wrote Cuoco. "There have been many precious lives lost over the years but even so, we still make this happen."

Cuoco explained the story behind the photo.

"Someone showed me this photo last night," she said. "My Grams is right there in the middle.. Through all the craziness, drama, gossip, tears, and life that has happened this last year, seeing these people who know me quite well, made me oh so very happy."
