This is a song about a woman who realizes it's time to go. 

I don't know what you want from me, 
But I'm starting to see it can't be given. 
If I spend all my life trying to make you happy, 
Well, that's not really livin'. 

Problem is that I've loved you since the day I first saw you, 
But I can't take the pain anymore. 
So I'm packin' up My Blue Suitcase, 
And I'm shufflin' out the door 

You work so hard for your misery, 
It'd be a shame for me to deprive you of it. 
I've known a lot of folks with a lot of sufferin', 
But you're the first I've seen that really seems to love it. 

Problem is that... 

You've got a hole in your self-esteem that I can't begin to fill. 
You've got a rough road 'til you get over that hill. 
Hope you will, but still... 

Misery loves company, but it's a love that's unrequited. 
All I can do with my feeling for you is use all my strength to fight it. 

Problem is that...
