Help on what i need to improve on im a 16 year old boy who enjoys free writing poetry

[_nothinglastsforeverbutlove_]

This heart of mine was once whole
Now it is broken to little pieces
I tried the best I could to hold us together
But my best was not good enough
And I'm sorry I failed you
I'm sorry that I want good enough for your heart
I apologize for the stuff I cannot change
And what I cannot control
You are the love of my life
But I shall be in eternal darkness forevermore
It is not your fault it is mine for believing
For believing that id ever be good enough
For one so special and beautiful
I guess it was too much to hope for
It was a dream I never wanted to wake up from
But I am awake now and feeling
The pains of forever promised
Go into the wind
My dreams hopes love and heart have gone with the wind
