How to mend a broken heart

I have to run the fast as I can and never look back again
I have to throw this heart away
Thay's the only way I might stop thinking one day you were real to me
I just wanted to lock myself away very very far until this goes away
Always knew what to do
But this time
I lost myself in you
And now I am just fragments of who I was scattered all over
Trapped in memories
Trying to find what was left of me
With no illusions this could ever work
Maybe it was never meant to be
I thought I had enough love for both of us
When all you wanted was a friend
And I understood everything wrong
Believing when you said I was the one
Because I knew from the start
I would ended hurt
However I let go of the fear and allowed me to love you
And I fought for us
And nothing I could do was enough
To make this happen
No i am here
Just grieving on what it could have been
And it'll never be
I made a choice and it was you
You turned your back on me
And close the door to your heart
I am just an abandoned heartless
Begging for some love
This poor heart of mine
Will never recover this time
Since its pieces are never to be found
Left in the places we had been before
And leaving me just a small piece all broken in uneven parts
So no glue could ever mend it
Maybe some tape it'll do the job masking it
I just don't know how to give this love for someone else
If I was waiting all my life to give this to you
