I'm alive or dead....???

So many times I stopped to breathe,
Just to confirm I'm alive or dead?
No soul was there,
Everywhere, I'm lonely.
Things that I lost could I get again?
Inside the heart unhealing pain.
I'll feel you then,
In every rain, I promise.
Give me the reason why you walked away?
What was my fault, you need to say?
Leave me now, I'll find you where will you hide?
I'll love you from all the pieces of my heart.
