cracked - finished

To set the bridge apart from the verses I altered its rhyming scheme by shifting two lines:

once he left his home to make his luck
once he was a young man full of hope
pursuing his dream of making a quick buck
now he has sold his future for some dope

Better!

Here's the complete text:

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

he's cracked
this boy is cracked
he won't get back on track
this boy is cracked

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

he's cracked
this boy is cracked
he won't get back on track
this boy is cracked

once he left his home to make his luck
once he was a young man full of hope
pursuing his dream of making a quick buck
now he has sold his future for some dope

he's cracked
this boy is cracked
he won't get back on track
this boy is cracked
