Mallerie Ban, quoted in an ADHD aha interview, described how she put perfectionist expectations on herself as a child not because her parents demanded it, but because 'making any type of mistake just wasn't an option ever,' leading to a belief that if she made mistakes 'someone's going to find out and someone's going to figure out' she was not perfect; she felt she had to hide not just mistakes but other ADHD traits (talking too much, not taking turns in conversation, bouncing legs, big reactions) because these would expose her as 'different,' and the fear of exposure created a domino effect of masking.
