Amy Schumer fans applaud the actress’s bold confidence, but she says she has long struggled with insecurity about her body image.

In an emotional interview with Maria Shriver on the Today Show, Schumer said her body image has “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 something [I’m wearing]. And sometimes, I would just want to throw in the towel and be like, ‘I’m not gonna go do stand-up tonight.’”

But after getting help from a stylist, Leesa Evans, on the Trainwreck set, she felt much more confident. After she grew close with Evans, the stylist also helped Schumer’s sister pick out more flattering clothes. Schumer teared up talking about this, and said, “seeing my little sister wearing a little blazer and a shirt and looking just like a strong, beautiful woman, it was … to see this person I care the most about being given those tools was really moving for me.”

Schumer has undertaken a project in partnership with Goodwill to help other women dress their best to feel more confident. Her first HBO special, Amy Schumer: Live at the Apollo, premieres on Saturday.
