The space where you're not

[FayandFire]

Feeling fresh, free and full hearted.

My mind bends and sways to new sounds.

The height of happiness hits empty space... ( the empty space) assuming your talking about a specific person they would take up a specific place

...where you are not.

It engulfs me and silences my mind...

...then there you are.

Suddenly with me, but really you're not.

We nod and agree, but really we don't.

I smile right back at the space where you're not.

I know I'm mad, my heart sinks and shrivels.

A split second of near suffocation,

And squinting to hold back my tears from you.

And then you are gone...though really you're not.

You'll always be there...and i'm with you too.

I really enjoy the first four lines. I feel like there could be some grammar issues but I'm not good enough at grammar to really be sure. All in all I enjoyed this ( and could feel it) but I'm no expert!
