I feel 'fine'

The birds joyfully sing
Butterflies lightly bat the wing
The sun brightly shines
And I feel just fine

It is a great day
I feel perfectly fine
But you seem sad, they say
Stop, you just crossed a line

Don't worry I reply
I am still perfectly fine
My problems don't concern you
This whole story is “entirely” not a lie

Okay, I'll tell you the truth, fine
I feel horrible, I am not fine
My world just crumbles from inside
I just need someone standing by my side

Are you happy now
Now that I have tears in my eyes
Every time I have said that I am fine
All of that were just big fat lies
