I'm not so sure

As I lay down I can't help but think to myself
My past, my present, my future
Each one terrifies me more and more as the days go on
I can't help but indulge myself in the bitterness of my past
What if I had just changed one small detail...
Would I have been better?
For the road I walk on now I don't know where I'm going
I just hopped on and ran with it
And that's all I can keep doing
Running
My future is one horrifying thing
I'm not sure what it holds
I'm not sure I want to know..
I just want to keep running
And running
Til I'm
Gone
