“Some nights I didn’t even want to go on stage because I couldn’t find an outfit I felt good in,” Amy Schumer told Maria Shriver in an emotional interview about body image issues that aired on Friday’s edition of the TODAY show.

Schumer, the Trainwreck star and recent Saturday Night Live host, revealed her struggle as part of promotion for her partnership with Goodwill of Southern California “to educate and inspire women through fashion.”

“It’s an emotional thing,” Schumer said. “It’s been a struggle for me my whole life, and especially just being in the entertainment industry. Standing on a stage in front of people, I can’t perform my best or be confident if I’m not sure — if I’m pulling at [my clothes]. And sometimes I would just want to throw in the towel and be like, ‘I’m not gonna go do standup tonight.'”

Schumer said she gained confidence in her clothing choices after working with Leesa Evans on the set of Trainwreck. “My sister and I, we both have always dressed badly. Leesa had given me this gift of showing me how to dress and feel good. And she didn’t have to do this, she just did. She shopped for my sister also, and seeing my little sister wearing a little blazer and a shirt and looking just like a strong, beautiful woman, it was …” Schumer said, choking up. “To see this person I care the most about being given those tools was really moving for me.”

The breakout actress and comedian has discussed confidence and body issues in the past, perhaps most memorably during a speech in May at the Gloria Awards and Gala, hosted by the Ms. Foundation for Women.

“I am a woman with thoughts and questions and sh– to say. I say if I’m beautiful. I say if I’m strong. You will not determine my story — I will,” Schumer said. “I will speak and share and f— and love and I will never apologize to the frightened millions who resent that they never had it in them to do it. I stand here and I am amazing, for you. Not because of you. I am not who I sleep with. I am not my weight. I am not my mother. I am myself. And I am all of you.”
