I must have been out of my mind

I must have been out of my mind
To ever let you go
I must have been out of my mind
To ever hurt you so.

I didn't know how much I cared
Till you found someone new
I look back at all that we shared
And how your love was true.

I know that as long as I live
You'll be my one regret
Because you had so much to give
Your so hard to forget.

And now that I see, what you mean to me
I wonder why I was so blind
The only answer can be
I must have been out of my mind.

(I know that as long as I live)
You'll be my one regret
(Because you had so much to give)
Your so hard to forget.

Oh, and now that I see what you mean to me
I wonder why I was so blind
The only answer can be
I must have been out of my mind
