I asked my therapist about how he helps individuals that struggle with "we". He told me that what his patients learn is how to acknowledge and comfort the different parts of them and learn how to function with their dominant part that has been that part in them that coped and functioned in spite of their traumatic history. He told me one of his patients was actually a top CEO and prominent and that individual had to learn how to make sure when he engaged in his career that he did so with the part/identity in him that was the one that was very good at doing his career.

With your therapy, the goal should be to slowly learn how to manage all of your parts, no one should have to struggle and feel lost inside you. You need help in learning how to manage because you most likely have not quite learned how to do that "yet". That "yet" is always important to remember because whatever you don't know how to do right now never means you cannot "learn" to understand how. Therapy is getting help to learn what works best for "you". It doesn't have to happen all at once either, it's something that you should be able to work on gradually ok?
