The Real Me

I act so happy,
But no-one can see,
That this is definately not,
The real me,

People see me as bright,
And happy constantly,
But everytime I'm sad,
You just leave me be,

I cry invisible tears,
Right in front of you,
But no way would I say,
My life is through,

I want to tell you,
How sad I can be,
Because then you would know,
The real me
