The latest episode of "The Big Bang Theory" season 9 had a lot of feels, especially since Sheldon Cooper (Jim Parsons) and Amy Farrah Fowler (Mayim Bialik) started hanging out again after their split.

Amy really enjoyed her Thanksgiving date with Sheldon, and Sheldon actually felt the same way. But after, when Amy suggested that they get back together, Sheldon turned her down because he considers getting over her the hardest thing he has ever done.

Bialik shares Amy's heartache, so she considers it one of the most difficult scenes she has ever done. She even talked about her feelings about it in her blog Groknation: "The hardest part about this episode is that in the final scene, we see Amy mistakenly assuming that since she was the one to throw the brakes on the relationship that Sheldon was simply waiting for her to hit the gas again. In what was a heartbreaking scene to perform and - as I am told - to watch, Sheldon declares that he is not ready to open himself up again to the possibility of being hurt. Ouch. The episode ends there."

Bialik then said that the reason why Amy looks so sad when Sheldon turns down her offer is that Bialik herself felt extremely sad and vulnerable.

"I don't know that it is ever easy to sum up what it is like to perform a scene like this as an actor," she said. "What I can tell you is that I think I am actually a very bad actor because a truly good actor would be able to act heartbroken when they weren't.

I acted heartbroken because I felt it very deeply."

Bialik refused to tell fans what will happen next in Sheldon and Amy's story, but she assured everybody that they will not be disappointed because she was far from feeling that.

She appreciates how moved people were by the last episode, and it means a lot to them all that fans have invested so much on their characters and stories.

"It means a lot to our writers and to us as actors that we have such a loyal and enthusiastic set of fans that care so deeply about all of these characters," she said. "As Amy, I get to act out a lot of emotions and feelings that many of us are conditioned to not express or talk about. For that, I am grateful to our writers for allowing those parts of themselves to be expressed through our characters."
