Running through my head

As I'm sitting here alone, I have you running through my head non stop.

I just can't seem to get you off my mind. Even though we've had our ups and downs, I still think about you a lot.

It's mostly when I'm alone, that's when you're always running through my head.

I don't really mind it, except when it's something that brings tears to my eyes. That's the only time I wish you weren't on my mind.

There's just something about you, that has you running through my head all the time; whether we're getting along or not.
