To The One Who Can't Close His Eyes

[busker]

Yet you’ve tried to pursue me,
Old man, you could never see the
Ultimate folly: we were not meant to be. 

Wise, you clearly are not,
Ill-stricken, you surely are.
Lustful lover of me, yet
Loser of thee, for you will never,  ... you've spoken a lot of words by this point, but conveyed very little information

Nestle beside me in the hush of dusk.  ... 'we were not meant to be' has said this already
Eyelids drift, but you remain wide and wanting.  ... the only good line in the poem
Veins twitch with grim unrest.  ... 'grim unrest' is an original phrase, and not a particularly exciting one. Might as well say 'black unrest' or 'dark unrest' - they are as boring. These are filler words.
Every blink denies you my sweet gift.  ... but could he not not close his eyes? 
Rest, I promised. Yet listening failed.

Can you not see how
Anguish twists in your limbs?  ... 'anguish twists' is not evocative. Also, by this point the reader doesn't really care about how this nameless old dude is dying
The aches between your temples, you’re a
Casualty to my teasing, fleeting hush.
Help me, help you, sleep forever more.

My long-lost friend, could you never tell?  ... cliches underlined
Eternal slumber waits at the end of your waking knell.

Hi meadz - the crit in Intensive is somewhat no holds barred, so I hope you'll take it in the right spirit.
There is a story being told here, but there's no context, nothing that gets the reader invested in the subject or the speaker.
The characters are not fleshed out. 
No hint regarding the motive or the participants' identities.
The acrostic doesn't do it either. It raises yet more questions, and not particularly interesting ones.
The lines are repetitive and / or dull. 

Needs a rewrite
