Jim Parsons Says He Was ‘Miserable’ at the Height of ‘Big Bang Theory’ Fame

The award-winning actor is getting candid about the emotional cost of his years on "The Big Bang Theory." He admitted that some of his most celebrated moments were also his most miserable.

Jim Parsons is opening up about what became a trying time at what was meant to be the height of his career. The 53-year-old actor was starring in "The Big Bang Theory," the comedy series that shot him to superstardom, but that success came at a cost.

Parsons reflected on his career and his years on the show during an appearance on the "All Out with Jon Dean" podcast. "I look back now and realize that there were many ways, at some of the best moments of my life, I was miserable," he shared.

"I was not happy. I was stressed. I felt that there was so many plates I was supposed to be keeping in the air and that the success and the good things of life that were happening were only due to this overworking [...] discipline and whatever," he continued.

"Maybe to a degree that was true. I don't know. I can't say because that's how I was," Parsons said.

Though his work as Sheldon Cooper earned him numerous prestigious awards, he's since made peace with the fact that the toll wasn't worth it. "I wouldn't do that again and for any amount of money. [...] It was stressful and miserable at times. I made myself miserable," he shared.

When host Jon Dean asked whether that pressure simply came down to his "work ethic," Parsons clarified that it was only part of the picture.

"It translated in part into a work ethic, but it was really just obsessive behavior basically," he admitted. "Yes, I was disciplined. Yes, I had a good work ethic, but a lot of it was because it was kind of OCD in nature."

"I had a list of things basically in my head that I had to get done in order to be comfortable and know that I could do my job right, which I don't think was true," Parsons shared. As a result, he felt he missed "tons of life."

Dean then asked whether Parsons would advise young actors, suddenly booked and busy, to guard against letting their careers eclipse everything else, or if he believed there was a way to strike a balance. "I don't honestly know," Parsons replied.

"In the same way, I can't go back. I wouldn't be where I am right now if I hadn't had that time of life and that somewhat self-tortured nature was part of it. So, I don't know what to tell people," he said. "I don't know how much of that is necessary."

Elsewhere in the interview, Parsons acknowledged that while being recognized for the role "is not going away," his relationship to it continues to shift.

"It's evolving, and it gets better all the time. What I feel is better, what I feel is healthier. It's not something that I think probably anybody, but I was certainly not equipped to, looking back," he shared. He also described fame, to him, as a "very odd psychological thing."

Beyond that, he noted it's even stranger to consider that most people only know him as a character he no longer plays, and hasn't for seven years now.

Parsons played Sheldon on "The Big Bang Theory" from 2007 to 2019, earning a Golden Globe Award and multiple Emmy Awards along the way. These days, he stars as Rose's Mother in the Broadway production of "Titanique."
