Yes,
I know this experience. Or at least my version of it.
For me, they are all parts of myself and while it might be a cliche I still feel like there is a lot in the explanation that when the parts don't get along it mirrors the conflict I was used to in those around me, family and society, particularly growing up.
I think everyone had a version of this to some extent, although not everyone is aware of it or minds it if they are: we all have different parts, it's a pretty human thing.
I don't know about who the person is that says one part of you has to be in charge. But I dunno...I can't help seeing the irony of that person imposing their opinion on you so freely, I guess it's not hard to see why they think that way ;-).
I find it helps to listen and get to understand the different parts of me. Usually when they are in conflict or seem fragmented there's a reason, like a conflict between say on the one hand wanting someone's approval or fearing what they'll do if we have our own opinion, on the other hand naturally having our own opinion and wanting our own autonomy and mutual respect.
Sometimes the outside conflict doesn't seem resolvable (eg, say we feel we really need or value that person or the power they exert over us is genuinely scary) then sometimes it can create inner conflict.
That's been my experience anyway. What's helped has been being able to work through it in a space where people do have mutual respect for me and genuinely want to help support me to finding an understanding of myself --- my understanding of myself, not theirs. Such people can be hard to find, and did have to be looked for. But I have found them well worth the search. The experience of genuine mutual respect has been quite amazing after it had been compromised for so long.
Unfortunately, not everyone who hangs out a shingle in the 'mental health' space has done their own inner work. And there is still an unfortunate amount of 'medicalisation' of people's living problems, without letting people know that is an analogy, not a 'fact'. I've found it really harmful that, among other harms, medicalisation couldn't encourage or support "looking under the hood", learning to understand myself as a person, in a context of other people - who I needed by my side, not looking down on me.
But there are changes happening and people who don't impose these things around (though unfortunately can still be hard to find). Finding people like this has been invaluable to me, without that genuine support everything was just a "symptom" or else something I was completely alone in trying to understand.
Now it's like slowly getting to know all the parts of myself that have been buried. And as I do it helps me resolve things and my parts get along better and better, get to know each other, work together as a genuine '''team" held together by mutual and self respect..
It's not been instant, by a long shot..but in time it's getting pretty awesome.
I guess it's like the outer 'team' becoming a bit of a role model or testing ground for the inner 'team'. But I can't stress enough how much that has depended on working with people who genuinely respected me and didn't force me into their philosophies.. that can take a bit of wrangling in todays world :-? Though it's hopefully on the mend.
That's been my story anyway...hope it helps in some way
Best of luck to you matey.
