McKell, it doesn't have to be "mystical" or the "inner child" but just imagining (as my T worded it once) if you had your own daughter who was that age with the problems you had, what would you do for her, say to her, how would you comfort and care for her?

I've felt various ages in therapy, usually somewhere in the older teens. But my "inner child" was somewhere 2-5 years old and not the most verbal child in the world :-) so was heck to work with. Sometimes photographs helped; do you have any pictures of yourself at 10? Just gently excavate around your 10 year old self, what school you were at, if you remember any of your friends or classmates, route to school, what you liked to eat, etc. and more and more memories will come back as you do so.
