cracked - II

I've completed three verses for "cracked". After shifting a few lines to and fro I think they're not bad for the time being. I've altered the rhyming scheme to AABB because the lines somehow seemed too long to work well with an ABAB rhyming scheme:

the boy is longing desperatley
  for another high
he doesn't know how he can make it
  yet another night
a million nasty, tiny bugs
  crawl under his skin
will he be able to go hustling
  in the state he's in

he's scratched himself because his body's
  itching everywhere
his skin is torn, and bruised, and bleeding
  - it's so hard to bear
he knows that he is slowly losing
  touch with reality
he needs another shot quite soon
  to keep his sanity

since what feels like a week
  he hasn't slept a wink
he has a hazy notion that
  his life is on the brink
there's someone there on his heels
  or maybe he's insane
yet no-one there who he could turn to
  who would end his pain
 

My favorite rhyming dictionary http://www.rhymezone.com helped me yet again to find useful words, this time these were "brink" and "pain".
