Keeps On Spinning..

Even though I am laying down,
The world keeps on spinning,
Try to get my thoughts in order,
Inside a mess but outside I'm grinning,
Not sure how I'm feeling,
I'm up and then I'm down,
Changing from a smile quickly to a frown,
It's hard to keep up,
Just don't know where to start,
The uncertainty of it all is tearing me apart..
