The Cooper family has signed off the air for good.

After seven seasons, Young Sheldon aired its moving, two-part series finale on Thursday, May 16. Cast members including Iain Armitage, Raegan Revord, and Annie Potts paid tribute to their time on the CBS comedy, showing their love on social media.

Armitage, 15, who played young Sheldon Cooper, posted on Instagram, “I’ve always wondered what this day would feel like and now it’s here! Thank you for a wonderful ride. I will miss everyone so much and I want you to know that it’s been an honor to play this part, and it’s been a joy to work with people I love so much.”

“I’m excited to see what’s next and I hope you’ll join me on the next chapter, whatever that is. ❤️ I truly hope you enjoy the finale. It was made with a lot of love,” the actor added, alongside a photo of himself posing on a couch.

Revord, 16, who played Missy Cooper, posted a video featuring moments from their time on the show, alongside the caption, “Over the years I’ve watched a lot of my favorite shows have their series finales and one thing I always thought about is how heartbreaking it must be to say goodbye, never thinking about my own because it seemed so far into the future.”

“Here I am on the day of my own finale heartbroken. I love this cast, our incredible crew, and these characters so much not having them in my life everyday seems impossible. But I’m also filled with wonderful memories, a beautiful childhood, a family forever, and gratitude,” Revord continued.

“Thank you to those that have tuned in over the years and for loving these characters as much as we do. I hope you enjoy the finale tonight, it’s some of the most beautiful episodes of  TV I’ve ever watched. ❤️”

Sharing a photo alongside Coach Dale Ballard actor Craig T. Nelson, 80, Potts, 71, who played Meemaw, wrote, “❤️Love and Gratitude for 7 great seasons #YoungSheldon.”

Caleb Emery, 30, who played Darren, posted a grab of him and Armitage on his Instagram Stories, writing, “Congrats to this guy! What a run! Glad I was a part of it!”

Pastor Jeff Hodgkins actor Matt Hobby was among those posting about the finale, writing alongside two photos, “My first day at Young Sheldon, and my last day at Young Sheldon.”

“I’m so grateful to have been a part of this wonderful story for 7 years. I will miss these kind, genius, loving people. I’m so proud that this will always be a part of my life. #youngsheldon,” Hobby added.

Wyatt McClure, 15, who played Billy Sparks, added, “Bittersweet day today. Series finale of Young Sheldon is on tonight. Although the end is coming I have made lifelong friends forever.”

“Get your tissues ready. Thank you to everyone on the show who made this the greatest 7 years possible. Looking forward to the next chapter!#cbsyoungsheldon #cbs,” McClure added.

Melissa Joan Hart, 48, who directed a handful of episodes of the show, shared multiple snaps with the cast on Instagram, writing, “Bittersweet post about the series finale of @youngsheldoncbs tonight!”

“I had the absolute honor to direct a handful of episodes for this groundbreaking show with this incredible cast and so many icons coming thru the door as guest stars as well! What’s a ride and congrats to all my friends on a show that made people laugh, cry and come back to appointment television! #YoungSheldon.”

Nora guest star Kate Flannery, 59, wrote on Instagram, “Congratulations @youngsheldoncbs What a great run! Thank you @iain you are a smart, funny, and very kind soul. It was so great working with you. A finale is a graduation! Thank you for letting me be a small part of this lovely show a few short years ago. ❤️ You did it!!”

Vyvy Nguyen, who also guest starred on the show, then shared a cute clip on Instagram of her and Armitage having an “oink-off,” writing, “I had the absolute best time working on the show, playing the mother to Tam, Sheldon’s high school best friend, and it’s been so fun to receive messages from people discovering it on Netflix.

In exclusive interviews with PEOPLE at PaleyFest 2024 in April, the cast reflected on the years they spent together filming the beloved CBS comedy.

“It’s been very bittersweet. It’s not an easy thing to know that something that’s been so wonderful for us is coming to an end,” Zoe Perry, 40, who played Mary Cooper, said. “But I think I can speak for everyone that we’re all just really grateful that we’ve gotten to tell this story, tell it for as long as we have, get to experience the audience reactions and how wonderful they’ve been. I think we’re just so appreciative. Truly.”

Montana Jordan, 21, who played Georgie Cooper, described his castmates as a true-blue “family,” even when the cameras weren’t rolling as they did activities together outside of work. Revord in particular, bugged him “all the time” via text “to do stuff.”

“I got two older sisters in real life, and on the show I got a little brother and a little sister, so I got the best of both worlds,” Jordan said, adding, “We’ve been a family ever since the first day we met — and we’re still a family. Just because the show’s ending don’t mean we’re not going to continue being a family. That’s what kind of bond we got.”

Potts, for her part, grew emotional when PEOPLE asked her at the same event about her experiences working with Young Sheldon’s younger actors.

“They were this big, and now look at them,” she said. “My God, they all turned out so beautiful and so sweet, and we feel like we had a hand in raising them … When we started out, they would sit in my lap and just play with my fingers and kiss me and tell me they love me all day long. That, and they still do actually.”
