Wow, I love this. I like how in most of the brackets it's a contrasting phrase to what came before it. I also liked how you managed to make it rhyme, despite it's complexity.

Really good.

I loved this, absolutely loved it. I also really liked the brackets, it really added to the effect of the poem.

"Words are easy, to speak (so much harder to mean)"
^^ I think it would sound better without the comma. Maybe just me though.

"Hoping to leave (guessing I don't)
Standing in crowds (but still so alone)
Letting you go (because you're what I need most)
Today I quite like you (tomorrow I won't) "

^^ I fricken adored those lines, they really stuck out to me. Great job.
