Change lyrics

I feel unhappy, I feel so sad
I've lost the best friend, that I ever had.
She was my woman, I love her so.
But it's too late now, I've let her go.
I'm going through changes.
I'm going through changes.
We shared the years, we shared each day.
In love together, we found a way.
But soon the world, had it's evil way.
My heart was blinded, love went astray.
I'm going through changes.
I'm going through changes.
It took so long, to realize.
And I can still hear her last goodbyes.
Now all my days, are filled with tears.
Wish I could go back, and change these years.
I'm going through changes.
I'm going through changes
