Sugar coated

Some see me as a nice normal girl.
They don't know me though.
no one does.
They see all the innocence
and don't know I'm guilty,
when something has been done,
they all think it wasn't me.
they all think I'm happy
and i never shed a tear.
they think they know me
and everything is so clear.
The truth is,
they don't know what I'm going through.
how i have sleepless nights
and how i have a broken heart.
Is covering this up the right thing to do?
Is this what all teen age girls go through?
