Isn't it interesting that so many of the teen alters on PC appear to have trouble with Ts? I know how it is for teen alters to really take personally something T says. What I am going to have to do with mine is allow her to spend more "face time" with T than the other alters. I am even thinking of devoting every other session just for her! It will mean I have to "sacrafice" a bit of "my" time with T - which is very precious to me! But if that is what it is going to take to work through the issues burried that deep, then that is what I need to do. So my suggestion for you might be to give your teen even more time with T. Allow them the chance to work things out between them. DID is a very unique situation with therapy because it really is like bringing in different people along with "you" to the session. So personality clashes may arise. Be gentle with your system and honor the process of healing.
