One of the things that I have noticed about you (across various accounts) is that you often speak of a precious inner child of yours that needs protecting. Is this part and parcel to this personality fragmentation?
The inner child is a thing that is central to many therapeutical methods that deal with trauma healing.
I believe schema and lowen are some thought there may be others.
Basically your childhood is the period where you form yourself as the person you are today. Traumatic experiences shape what coping mechanisms you might develop as an adult.
Some are better than others in dealing with trauma and some are dysfunctional.
Trauma is tricky and although it can be healed, if is not we try to balance it through coping mechanisms, it’s then about luck and life circumstances if those mechanisms work well and resolve the trauma or they become emanations of trauma and the coping mechanisms are created to justify your dysfunction to yourself (basically reinforcing the trauma rather than resolving it).
Addressing the child is like addressing the you before and during the early trauma.
Emotional events don’t fade, they are carved in our psyche wether consciously or subconsciously, we bring them along. Trauma is a deep and scarring emotional experience.
If " the child" can feel safe about the things that caused the trauma, the trauma itself can heal, improve or completely disappear.
I think it’s that child she is addressing in her process.
