Wee morning worries

I lie awake sometimes, in bed, in the wee hours of the morning and I think. Better put, I brood – but not about a single topic. My brain goes from here to there, whizzing, whirring, round about from subject to subject and then back again to a previous one. At a time when my gray matter should be resting, it operates at a rapid pace because apparently at 4:00 am instead of sleeping and dreaming about happy things my brain thinks I should be doing something much more productive, like worrying.
