And Where Were you?

I never thought I'd see this day,
I never thought I'd feel this way,
You.......a stranger to me now.
I'm left with emptiness......
I wish I knew how it could be
That we were once so open and free.
You were like my brother....
And yet so much more..
I wish I would have seen,
What I see now...before.
For, I did not and its too late..
My friend, my best friend, is now unknown
And what hurts the most is, I now know..
What I lost..and I'm alone.
To face a challenge life has sent
And not a moment with you I've spent
I hope one day I can forgive you, my friend
I miss you...
Why did you go?
