Missing EDIT 2 technically

[RiverNotch]

I for one don't think there should be any dichotomy between poetry and song lyrics -- the oldest poems were apparently meant to be sung? and you have the likes of opera and Bob Dylan and such. The problem with this piece, besides the very clear lack of punctuation (seriously, even Shakespeare was punctuated -- the lack of punctuation, as earlier noted, makes it read like you don't give a fuck), is that it's very meh. The rhythm is inconsistent, the imagery is cliche, and the emotional punch lacks the precision characteristic of the good stuff. And I do think that even if you haven't experienced what you wrote about (or if you don't know anyone who has), you could still make it personal -- I think the trick is considering all pain as essentially one, treating the subject simply as a dense metaphor.

Maggie my dear "Martha, my dear..." Well, since it seems the dichotomy exists in a lot of people's minds, this isn't a good start.
The tension is heavy
I sleep in my Chevy 
all the time

I'm going crazy
Your picture's the only thing And here you break the rhythm, in a clearly strict-structured piece.
Keeping me company 
all the time

You gave your goodbye
Can't help wonder why
I wish I could fly And here, a prime example of blandness. How many singers have sung about strange goodbyes, about flying away? Worse still, about strange goodbyes and long fly-aways with these exact same words, this exact same lack of elaboration.
all the time

I'm only Vincent
I've covered the cost, much more than you're worth
I'm getting old, another rolling stone growing mold
If tears alone keep us warm, I'd rather be cold Though some of the ideas here still feel somewhat cliche (tears to keep warm, the very mention of a rolling stone), at least this tries to peak (I rather your way of describing ageing, rolling stone so and so). Maybe a good place to start from, for a rewrite?

I know you can't hear me
My words have grown weary
I miss you sincerely Again, bland.
all the time
