She feels as though she started out in a single straight-forward path, That could not have been daunted by even the biggest bump in the road.
Somewhere along the way she must have taken a wrong turn. She feels as though she has been walking for miles and her path just keeps getting harder to navigate.
She is lost.
Maybe she was too wistful, a hopeless romantic in the sense of Romanticism not necessarily love. She wanted her life to take a turn and finally take off.
In a sense she wanted to fly away from everything and forget the past completely. That in itself was a mistake.
No matter what one does to escape the past, Certain factors of it stick.
