i need a long beautiful poem about the topic: "i'm sorry"

i kinda messed things up badly with my best friends and i need a poem to show how much i care and to to tell her im sorry. plz guys i need your help!

I'm Sorry what i may have done,
For all the things that i've become.
So many days that pass us by,
There is no a single second i don't try,
To tell you how much i care.
And that out friendship is what i want to share.
But there is no telling what you must think.
This feeling makes my heart slowly sink.
(kinda sucks)
