Sylvester Stallone reveals how childhood abandonment, parental violence, and a traumatic psychiatric ward stay fueled his rise from homelessness to Rocky and Rambo stardom. At 80, the actor opens up about bulimia, anxiety attacks, regret, and the love he didn't experience until age 70—exposing the deep emotional toll behind his invincible persona. Stallone developed bulimia while obsessively maintaining extreme body fat levels (2.6%) for Rocky III, driven by an unhealthy relationship with his physique as emotional armor rather than genuine fitness.
