A quick question does the mid-life crisis only happen to people who don't have much self-awareness ?
Childhood issues seem to be the common theme. How was her relationship with her father? Somewhere along the line her emotional growth, and yes, I guess you could say self awareness too has be stunted.
She has reached a point in life where she must now deal with this. So on an emotional level, back in time she goes. I can't say for how long, but things get crazy and in her eyes, the pain, confusion and hopeless feelings she has are all your fault.
