Goodbyes are never easy — just ask Annie Potts, who is still reeling over the cancellation of Young Sheldon.

Potts, who was joined by costar and young Sheldon himself Iain Armitage, got candid about her thoughts on CBS’ decision to end the series after seven seasons. “This one was especially hard because I was completely unprepared,” she told Variety. “I was shocked. I mean, the No. 1 show on network TV, No. 1 on Netflix. We’re, I think, all that people watch on TikTok besides a couple of recipes for pasta. It just seemed like such a stupid business move.”

Potts continued, “Forgive me, but I don’t know. If a show is starting to drag or lag or have a lack of stories or whatever, then you kind of see it coming. We were totally ambushed by this.”

For his part, Armitage said he thought “we could have done a lot more” with the show. “I totally get what Annie means,” he said. “It’s also just hard in a really weird way that I can only really see if I step back and try and take a global view, which is hard. I mean, I’m not going to get to see Annie Potts every day. This is a real loss for me. More than anyone.”

CBS announced in November that the popular prequel to The Big Bang Theory would conclude its run with its seventh season. In a statement at the time, executive producers Steve Holland, Steven Molaro, and Chuck Lorre said, “Being able to tell the origin of Sheldon Cooper, and expanding the story to include the entire Cooper family has been a wonderful experience. We are grateful to our fans for embracing this chapter of the Coopers these past six seasons, and on behalf of the entire Young Sheldon family, we’re excited to share this final season with you.”

Per Variety, the show wrapped production last week. Potts said she’s still “really, really, really emotional” about it all. “I mean, it’s been half of Ian’s life, and it’s been a 10th of mine, but at 70, that feels significant. And, you know, it’s a little village that we have, and we’ve all taken care of each other and raised each other up,” she said, adding, “There will be a grievous hole in my life. There’s no question about it. It’ll get easier. Grief does, loss does.”
