I totally agree with sky_ .

I liked others ideas for calming the young part of you. I sometimes do this by drawing pictures of my older ego states protecting the younger one. One image in particular showed the smaller ego state curled up in the corner while an older one was removing a limp skeleten from the closet. It had the skeleten by the neck suggesting that it was no match for the older state and there was nothing to fear. .

Also, when I was dealing with fears that my T could some how hurt me. I just kept reminding myself that... "I could easily take her down.". It sounds stupid, but... It worked. Telling myself that she couldn't really harm me even if she wanted to helped.
