Lyrics of Trouble in mind

Trouble in mind i'm blue but i won't be blue always
Because the sun's gonna shine in my back door someday
I'm gonna lay my head on some lonesome railroad line
And let that 2-20 pacify my worried mind

Trouble in mind i'm blue and i almost lost my mind
Sometimes i feel like livin' sometimes i feel i could die
I'm going down to the river i'm gonna buy me a rockin' chair
And if the blues don't leave me i'm gonna rock away from here

Trouble in mind i'm blue my old heart is a beating slow
I never had so much trouble in my life before
My good gal she done quit me and it sure did dread my mind
When you see me laughin' i'm just a tryin' to keep from cryin'
