Sebastian Maniscalco OPENS UP About IMPOSTER SYNDROME, MENTAL HEALTH & His Parents' Divorce

He describes a persistent internal narrative that questions whether the career will end, whether audiences will show up, and whether he has “peaked,” and he says it shows up in daily life more than as a pre-show ritual.

He says the early years were sustained by a belief he could make people laugh, a willingness to work constantly (including waiting tables), and a focus on what he could control: getting funnier, not tracking others’ success.

He describes his parents as supportive but also intensely critical, with his father pushing him to stay sharp and never get complacent; he also recognizes he sometimes carries that same “potential/you could do better” lens with his own kids.

He says surreal career moments (working with Scorsese, De Niro, Pesci, Pacino) were hard to enjoy because anxiety and insecurity made him assume the worst, even in neutral situations like colleagues huddling without him.

He explains that comedy rewards a mind that notices and reacts to irritation, absurdity, and anxiety—like an “allergic reaction to society”—which can be useful on stage but hard to shut off in everyday life.
