my two cents...
she was passed around from pillar to post so often she'd be totally confuddled about where she comes from in the first place. 'we cant know where we're going til we know where we've come from.' this can also be an issue with adopted kids at some point in their life. does she have any pix of her mom and her when she was a baby? has she talked at all about her mom? her babyhood? anyone else in that part of her family? or those who looked after her thru all this upheaval? is there any possibility of abuse of 'any kind' during her time in transit?
you've got a long road ahead of you and i do hope you can figure out what is going on with her so you can help her along lifes journey. hugz to both of you, jeanne
