I know, I knew

[spazzica]

Your eyes were the perfect chasms of passion,
and I fell so instantly and repeatedly.
So willingly and drunkenly.
I fell while grasping madly at the teasing glimpses of happiness.
The fears I’d once mocked, now surfacing bold and threatening.
Insanity whispers and ushers me along a perilous path.
I know, I knew, but now I care.
Though my tongue dances frantically on the taste of everything bitter,
my mind’s streams collecting into a poisonous river of thoughts and thoughtlessness.
You ask me to speak,
but I hold my breath.
My words pouring unfiltered from an internal haze, but faltering behind barricaded lips.
I hold my breath.
My tears, silently waiting to emerge, but flushed swiftly into emptiness.
There is no malice in your heart.
Only the remains of our selfish desires, uncertainties scattered in every hidden corner.
I still crave your touch, your scent, your smile. I crave forever.
I know, I knew, and now I remember.

Your eyes were the perfect chasms of passion,
and I fell so instantly and repeatedly. I would change this line to "I fell instantly, repeatedly,
So willingly and drunkenly.then I would change this line to "willingly, and drunkenly."
I fell while grasping madly at the teasing glimpses of happiness.
I would put a break here. I like to break up my poems into different stanzas, that's just me though so no need if you don't want to

The fears I’d once mocked, now surfacing bold and threatening.
Insanity whispers and ushers me along a perilous path.
I would put a break here.

I know, I knew, but now I care.
Though my tongue dances frantically on the taste of everything bitter,
my mind’s streams collecting into a poisonous river of thoughts and thoughtlessness.
I would put a break here.

You ask me to speak,
but I hold my breath.
My words pouring unfiltered from an internal haze, but faltering behind barricaded lips.
I hold my breath.This line is redundant, I would get rid of it.
I would put a break here.

My tears, silently waiting to emerge, but flushed swiftly into emptiness.
There is no malice in your heart.
Only the remains of our selfish desires, uncertainties scattered in every hidden corner.
I would put a break here.

I still crave your touch, your scent, your smile. I crave forever.
I know, I knew, and now I remember.I really like this line, it flows nicely

Overall, I really like what you are going for here. I like the thought behind this poem. There is just a lot of formatting I would change. Personally, I like breaks in my poetry, I like to place similar thoughts together in stanzas. I don't know if you'll agree with how I broke up your thoughts but its just my opinion. Also, some of your lines seem a little long. It just might read a little better if you split them up. For example if you broke up your poem the way I have, your second stanza could read:

The fears, once mocked, now surfacing,
bold and threatening.
Insanity whispers
and ushers me along a perilous path.

Just my opinions though, good start though
