The past did affect the present and the future.
In way you could divide easily:
There was no defined middle or beginning or end.
I could pretend to leave the past behind.
But, it would not leave me.
It always came back in tiny pieces.
And, always at the wrong time.
I would be sitting in class.
And, a teacher could say one simple word and it would give me another look at my past.
Each flashback was dragging me back to how I used to be.
I was so scared to be that person again.
And, I was determined to not let that fear grasp me and pull me under its spell.
I had a chance to change.
And, you only get so many do-overs in this life.
So many chances to, if not change your past, alter your future.
