Very well done. Very well done. How many friends have we had that offer critiques out of friendship and caring, out of respect? Your idea and feelings came through nicely. You did have a few errors in your grammer, but not enough to hurt the poem. I will say, you could have used " 'cuz," instead of "cos." I think it's acceptable here. And on one of your stanzas, might I offer a change?

I think of the many words of advice you gave,
I think of the precious gift of friendship that I now have.
I think that every person deserves a gift as precious as you,
But I know it's true you deserve someone better for you're one amongst them special few.

How about:
I think of all the advice you
gave for my sake.
I think of the friendship you've given,
not just for me to take.
I think every person deserves a gift
as precious as you.
I think you deserve much better,
because you're one of those speacial few.

I hope this helps in case you want to edit your poem. It's up to you. Although, your message still comes though none the less. Still, I think I'm adding this poem to my favorites list.

I want to hold in my hand the treasures you gave,
Take every step as my own - not a slave.

I think the line should be changed to "not as a slave" but thats just my opinion. Thats how i wanted to read it.
I really do love your poems. There long but thoughtful and keep the reader interested. They arent the kind of poems that your surprised for the ending but the kind of poems that your sad that it ended :)
5/5

Great work of suspence and thrill of emotion you know what i mean? anyway great read keep it up 5/5
