Kaley Cuoco has had quite the crazy 2015. She announced her divorce from Ryan Sweeting after 21 months of marriage, turned 30, kept busy on the set of "The Big Bang Theory" and denied romance rumors with co-star Johnny Galecki. 

Cuoco took to Instagram to reflect on the year and thank her family for their support. 

"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,” the “Big Bang Theory” star wrote.
