Those Sunshine Rays

I say there's nothing
wrong with me,
But they don't know,
They might soon see.

I hide my feelings
from my friends.
They don't know, that for me,
this could be the end.

One day I think
that I can fly,
but mostly I think
I'll drop and die.

Why does life have
to be this way?
Why don't I feel
those sunshine rays?
