And this is how I feel today:

Runaway train, never going back
Wrong way on a one-way track
Seems like I should be getting somewhere
Somehow I'm neither here nor there

Can you help me remember how to smile?
Make it somehow all seem worthwhile
How on earth did I get so jaded?
Life's mystery seems so faded
I can go where no one else can go
I know what no one else knows
Here I am just a-drownin' in the rain
With a ticket for a runaway train

Bought a ticket for a runaway train
Like a madman laughing at the rain
A little out of touch, a little insane
It's just easier than dealing with the pain

Runaway train, never going back
Wrong way on a one-way track
Seems like I should be getting somewhere
Somehow I'm neither here nor there
Runaway train, never coming back
Runaway train, tearing up the track
Runaway train, burning in my veins
I run away but it always seems the same

I'm not quite that depressed about it as the song sounds, but it's the same sense of being lost and perplexed. Do you ever feel like you're supposed to be going somewhere, and maybe you are, but you have no idea where you're going, or how you're getting there? Or like you've fallen off the train, and everything is rushing past you so fast, everything you want, but it won't slow down enough for you to jump back on?

"Like a madman laughing at the rain/ out of touch, a little insane." That's it exactly.
