Phew this is the first poem I've read in a while =D well anyway.. It was a great poem. I think it flowed well. I have one suggestion =)

Change the opening two lines to..

Every night when I sleep
There are a thousand things running in my mind..

PS. this is just a suggestion =)

I liked this piece, it was so vivid and realistic with the imagery used
it flows really well and comes together really neatly at the end
the line 'looking in the mirror, what do i see
a girl that has failed as a person, and as a friend' really got me
you write really well 5/5
