Kaley Cuoco is saying her goodbyes to The Big Bang Theory

The 33-year-old actress took to Instagram on Wednesday to share photos from the CBS sitcom's final table read -- revealing it was an emotional one for her in particular. 

"Yea, didn’t sleep . @bigbangtheory_cbs," Cuoco captioned a close-up of her script for the show's last episode, which is scheduled to air on May 16. 

Hours later, she posted a shot of herself in full-blown tears. "Post table read for @bigbangtheory_cbs finale episode," she wrote, leading Courteney Cox to share a supportive message. 

"Awww I remember that feeling," wrote the Friends star, who appeared on the iconic sitcom for 10 years. "And you guys have been together even longer ?♥️??."

Last came a photo of all the tissues Cuoco had cried through during the table read. "Prepare yourselves ... for a finale that has truly given me a loss for words ❤️ Our whole universe .... @bigbangtheory_cbs," she captioned the snap, as her Big Bang Theory co-stars also shared pics from the memorable day. 

Cuoco, who has starred as Penny on Big Bang since its first season 12 years ago, told ET in January that she was expecting a lot of tears during the show's finale. 

"I was laughing. I was like, 'How are we gonna shoot the last episode?'" she recalled. "I was hoping we were gonna pre-shoot a lot of it 'cause I think there are gonna be a lot of tears."

"It’s gonna be tough, it’s gonna be a lot of emotions and I love our crew. I just love the people that we’re with every day so, you know, all good things come to an end," Cuoco added. "Everyone is still madly in love with each other. We're all OK with the choice. We’ve just grown up together, so it’s our adult decision."
