Trouble in mind, I'm blue
But I won't be blue always
'Cause the sun's gonna shine
Round my back door someday

I'm going down to the river
I'm gonna take me a rocking chair
And if the blues don't leave me
I rock on away from here

Trouble in mind, I'm blue
But I won't be blue always
'Cause the sun's gonna shine
In my back door someday
[ Lyrics from: http://www.lyricsfreak.com/j/johnny+cash/trouble+in+mind_20324532.html ]
Trouble in mind, that's true
I have almost lost my mind
Life ain't worth living
I feel like I could die

Trouble in mind, I'm blue
My poor heart is healing slow
I've never had such trouble
In my whole life before

I'm gonna lay my head
On some lonesome railroad line
And let that 2:19 special
Ease my troubled mind

Trouble in mind, I'm blue
But I won't be blue always
'Cause the sun's gonna shine
In my back door someday
