I don't think roles help you resolve your issues. I just think they're good markers.
I was a big Guns N' Roses fan when I was seven. My friend who lived across the street had long dark curly hair and I had long blonde hair, so I'd dress up as Axl and she'd be Slash, and we'd rock out in front of the mirror singing 'Patience.'
I like people more undone than made up. Patricia Arquette is the ultimate. She's not anorexic or perfectly tan, she's not trying to be anything but what she is, and that's the most sexy thing.
I was a very imaginative and theatrical child and wasn't afraid of being in front of a camera.
