Maybe she is attached to her past because it is the one thing she has absolute certainty about.She escapes within and hides away in the depths that no hands can ever reach her, she is absorbed entirely.
Maybe she hides behind her past because it's the only truth she knows; She knows it will never escape her and leave her feeling empty.
For eternity she'll always find comfort in the fact that her past will always stay with her. She will dedicate herself to what happened, and what was, she will die wondering what could have been. And the possibilities that forsake yesterday's future. For today's future is always and forever completely unreachable.
She will fade through life only seeing memories and therefore never truly creating new ones.
