Awww.. this was good.. but very sadd.. it flowed well and contained alot of emotion.. the only part that i think could be improved was here ::

"A child screaming in our ears,
a mother calling out, in tears.
My eyes flickering, it was all a blur.
I realised only one thing, i was stupid.
A near death and three accidents,
because we chose to drink and drive."

^ i really wanted to learn more about what had happened.. i felt a little in shock after i heard the child scream and the mother cry.. i wanted to know what happened next, but you didn't explain.. so i think you could fix that..

Ever since that night we were mates.
Every weekend we would party away,
the envy of all our mates.
^ don't use "mates" twice, it ruins it a little..

good job, ill give it a 4/5
