The Little Things

I'm so scared of the little things,
Of things that shouldn't scare me,
Of things that probably won't ever be.
So many things scare me.
I worry about them almost constantly.
I can't seem to get these worries to leave me.
They're always with me.
It's driving me insane.
It's my biggest bane.
What's wrong with me?
For it's not the big things that scare me,
But all the little things.
