No turning back

I came to far to turn back now. I am tired, I do feel weak. But I Came far to turn back now! Everything looks a mess, you don't know my level of stress.
 I am a emotional reck. everything in me has been put to the test.
 I came to far to turn back now.
 I am miles away from where I was, not close enough to where I am going.
 My better days ahead I would be a fool to turn back now!
