Changes - Black Sabbath

Int.
1.
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
Ref1
I'm going through changes
I'm going through changes
2.
We shared the years, we shared each day,
In love together we found a way
But soon the world had its evil way,
My heart was blinded, love went astray
Ref2
I'm going through changes
I'm going through changes
3.
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
Ref3
I'm going through changes
I'm going through changes
