Silly story

I can't hide my feelings and still..
You don't see.
My heart is beating hard
but others are louder than me.

This situation is too difficult, to tell,
but at the same time it's really easy.
I don't need too much words,
maybe only three...

One with 'I', one with 'L' and the last with 'Y'.
In that three words, there's everything. I can't hide.
Maybe it would be easy to say, I don't know.
My voice is choked away, when I say: "_    _ _ _ _    _ _ _".
