While guest appearing at a conference at an LA high school, Gaga admits she struggled with bulimia during her own high school days LADY GAGA HAS MADE NO SECRET ABOUT HER PAST STRUGGLES WITH SELF ESTEEM AND BULLYING, AND NOW THE SINGER ISN’T HOLDING BACK ABOUT HER LONGTIME BATTLE WITH BULIMIA. THE MOTHER MONSTER WAS A SURPRISE GUEST AT THE “IT’S OUR TURN” YOUNG WOMEN’S CONFERENCE HOSTED BY MARIA SHRIVER, AT AN LA SCHOOL LAST WEEKEND…AND SHE DIDN’T HOLD BACK WHEN A STUDENT ASKED HER HOW SHE DEALS WITH BODY ISSUES: “I used to throw up all the time in high school,” SHE SAID. “So I’m not that confident. I wanted to be a skinny little ballerina, but I was a voluptuous little Italian girl whose dad had meatballs on the table every night.” “I used to come home and say, ‘Dad, why do you always give us this food? I need to be thin,’” the BORN THIS WAY SINGER ADDED. “And he’d say, ‘Eat your spaghetti.’” LUCKILY, GAGA SOON REALIZED THE TOLL HER EATING DISORDER WAS TAKING ON HER THROAT… “It made my voice bad, so I had to stop. The acid on your vocal chords … it’s very bad.” THEN SHE TOLD THE PACKED GYM OF GIRLS, “Every video I’m in, every magazine cover, they stretch you; they make you perfect. It’s not real life… “I’m encouraging you to know what you’re worth. And know that no matter who has more money and class, who has more stuff, who has a country house – nobody is worth more than anybody else.”
