Who is she? That she is me

I know a girl,
a girl who's always putting herself down,
a girls who holds a frown,
but on the outsdide she's happy,
as happy as far as everyone can see,
she cries on the inside because she misses her friends,
she laughs on the outside because there is no pretence,
she hides her face from the rest of the world,
she pushes aside her tears and forces a smile,
like the sun breaking free of the clouds imprisonment,
or like a beautiful rainbow arising after the rain,
she shines like morning glories,
although she feels unwanted,
she's surrounded by love,
she's surrounded by friends,
but nobody knows how she really feels, she feels alone and afraid,
scared and betrayed,
Do you know who? Who is she?
That she is ME.
