A Dear Letter for Absent Knives

I just thought I'd try this idea out. I know it's long but please let me know what you think.

A dear letter for my absent knives,
The ones with which I almost took my lives,
I'm like a cat, I have many lives,
In some I've lived, in others I've died,

In my first life i was very small,
Could hardly call it a life at all,
At the young age of three i died from fright,
When i watched that fight on that fateful night,
The one when my mother and father rowed,
It was horribly scary, as a secret it is vowed,

My second life lasted somewhat longer,
I'd grown up a bit more, become a lot stronger,
I had lots of friends, decent family life,
Didn't have many problems, didn't have much strife,
Then i had to move schools, would loose precious friends,
Totally uprooted my second life ends,

The start of the next one was full of teasing,
I was fat, ugly and teacher pleasing,
The one in the class that has few friends,
Is looking forward to a long, painful end,

Big school as my fourth life begins,
Full of excitement and wanting to fit in,
But something new happens at home,
And this time i die horribly alone,

The new thing-well he calls himself tony,
Tries to love and care but was really a phony,
When mummy had to dial nine nine nine,
My life ended in that house full of grime,

Next one, I'm living right here with my dad,
I look happy and cheerful and utterly glad,
That i left that dump but something else changes,
And now this is the sixth life in these cages,

I look along my cages filled with past lives,
The ones i would have lived in if i could have survived,
Wondering quite how i got here,
After crying out my every tear,

In my seventh life I'm a little girl,
One who's marks can make her hurl,
There are cuts and scars all up my arms,
Even though people try to stop my self harm,
I want to kill myself, i want to die,
But in my last life i need to survive,
But i don't want to live and i don't want to die,
Goodbye my dear, absent knives.
