Hi there. There are levels of the dissociation of different parts of the personality that lead up to DID which is at one extreme. Some theorists say that every single person has different parts of the personality. Pretty much everyone can talk about a part of themselves that is shy or outgoing, or moody, or playful or risk-taking and other things like that. It is the level of connection or disconnection between the parts that can cause problems. There is that kind of normal on one hand and then a huge range of different levels of connection between different parts self leading all the way up to DID on the other end.
From what you have written it seems like you have at least some connection between these different parts of yourself but experience some disconnection from them as well.
Have you ever read about family systems therapy? Or the theory of structural dissociation? They both talk about different parts of self.
