I was bored/scared 'shitless'.
(..) What am I so scared of? Well, what aren't you scared of? You live in this safe little world where no one challenges you, and you're scared shitless to do anything else. - Because that might mean that you'd have to change. - Don't, don't tell me about my world. Don't tell me about my world. (..)1997 Good Will Hunting
(..) something more than you love yourself. I doubt you've ever dared to love anybody that much. I look at you, I don't see an intelligent, confident man. I see a cocky, scared shitless kid. But you're a genius, Will. No one denies that. No one could possibly understand the depths of you. (..)1997 Good Will Hunting
