Hello Ousaima,
guilt and blaming herself is self-devaluation. The identity quest seems to be the doubt that he'll not be the right person because of her mom's and dad's relationship being her template. She suffers from the loss of contact and she tells herself that she doesn't want that contact. She doesn't know who to trust, where safety shall come from, and she blames herself for this. Therefore, her reaction of hair-pulling refers both to a separation theme and a a "auto-aggressive"  behaviour.
Territorial fear and territorial anger are both nuances of territorial conflicts by the way.
Good job!
