Vent... (Thoughts / Comments / Critique)?

My thoughts are heavy as concrete

Is it my mind, or just the heat

I've never felt this way before

I don't want to do this anymore

Wonder why I can't shack it off

Nobody else could break it off

Use to love to see your smiles

So far above,you must have been miles

Than anyone else I've ever been with

But I refuse to think that it's all a myth

Won't you come and walk with me

So harsh and humble you can be

Wish I could get out the words

Choked up, they fly with the birds

Yearning so much to tell her

I'm screaming, as loud as I can

She can't hear me, we never were

I'm screaming, until my lungs give

With this hole punched in my chest

I don't know how I use to live

Tearing up, I can't give it a rest

Wonder why I can't shake it off

She's the only one who could break it off

She's the only one

Who could break it in half...
