Why cant I sleep?

My mind has been just spinning.  Seems I can’t turn it off these days.  Things like “why aren’t we be like this … or how come I can’t do this, or that … or what’s it going to be like years from now, months from now … tomorrow?”
I can’t tell if things are moving too fast or too slow … sometimes not at all.
It’s driving me nuts.  
How can I turn it off?  
I think it’s some kind of evil past life conditioning.  I guess I just get a little insecure considering.  I haven’t enough alternative distractions.  I’ve been focusing on so few things lately just because I thought it would be easier.  Now, heck if one of those things falls off the radar just for a day or two … I feel like I’ve cut off a limb.  I miss it.  
It’s not fair.
I don’t think it’s suppose to be this way.  Or is it?  Damn it!
I hate this … I don’t feel well, emotionally.  Something is wrong.
I just miss her when she’s not around.  
Is that such a bad thing?
It’s just that’s it’s been so much NOT around lately than around.
Well … maybe a hot shower will help.
