I'm interested in how you met her in therapy? Did your T do something to evoke her? I first acknowledge my inner child late one night after a difficult therapy session. I've since acknowleged other inner "people" or ego states. I mainly tap into them via drawing. I don't particularly care for these often childish states. However, I have not been successful separating from them. I've recently taken the approach of just trying to find out what they are feeling.
