Which One Am I?

In the mirror, I see a chubby,
Brunette girl.
She has freckles
And small ears.
Her eyebrows are too thin,
Her skin too pale.
Look close when she smiles…
If she does.

In my mind, I see a stubborn,
Selfish girl.
Sometimes she tells lies
And other times, she says nothing at all.
She is afraid and nervous…
Scared of everything
I am often disappointed in her,
And so are everyone else.

In my heart, I know a
Simple girl.
She can be thoughtful,
She can be rude.
Sometimes she makes mistakes,
But always moves on.
The girl looks at life
And sees a puzzle waiting to be solved.

Which one am I?
