restless

I'm getting restless, keep finding myself daydreaming about getting in a car and hitting the road for awhile.
A friend mentioned that she and her husband wanted to take six months and volunteer their way around the country and it made me happy and sad all at once, thinking I want that too.
There are big changes brewing and I keep weighing pros and cons. I feel scared, uncertain, anxious, curious.
Change keeps my mind fresh, I ride that adrenaline high and forgo eating and live on bourbon and bubble gum. Am I running away? Taking a blind leap?
Or maybe there is no big picture, certainly my story is small and unimportant, and what I decide has little to do with anything but geography and libido and the kind sideways glance of fate.
