The 20-year-old actress had a panic attack during the first performance of her new play, All the Fine Boys, in New York City on Wednesday.

Breslin took to Twitter to describe the scary moment, calling out her cast mates, including Alex Wolff and Isabelle Fuhrman, for helping her get through the ordeal.

"When you're on stage doing a play and you have an actual panic attack mid show cuz anxiety doesn't warn you," she wrote. "BUT THEN your cast mates and crew give you tea and breathing exercises and the panic attack slowly packs it's bags and leave. BOOM."
