I am not overly fond of “parts” and have not let my therapist take it too far. That said... sometimes it really does seem as though I am feeling something or reacting to something from a much younger place within myself and “parts” does seem like the best way to describe and discuss the phenomenon.

This is not merely a conflict between logic and emotion or having several different feelings about something. It legit seems as though there’s a young part of me that, for example, is very wary of the therapist all while being absolutely desperate for her love and can only discuss this with maximal difficulty and awkwardness. This is not how adult me relates to her at all: the adult part trusts her, communicates openly, appreciates what she offers etc

It’s not DID, more akin to how you might see a whole new side of someone when you observe them speaking their home language for the first time and you only knew them speaking the language of the majority culture before. Or how someone’s personality might change after drinking a bit but before drunkenness. Something new comes out but it’s not like the adult with the frontal lobe is gone. You can’t “blame” parts. You use them to understands aspects of yourself and your history.
