14 year old alter
For me at 14 there was entry to high school ending a reenactment (sexual one) behavior clinging towards family sports and eating. Putting away a behavior and focusing on school. If I think this is my core self as well all have to do is separate those are would promote our switching her at P.C which is fine with me escapism. I'm going for cooperation not integration so make sure you align yourself with those that are promoting what is the best interest based on your testing of the waters. I would think the authentic self is to relate to you all in this forum on the topic. At 14, Since there is still a life to live I would focus on those few things that helped me understand my own history. I got an alter at 14 years old too those that help me understand to being vulnerable about its good and bad points is what I just mentioned here in the post. I still believe in grieving although mostly cooperation is necessary!
Good luck in your journey
