My response to-
-You refer to your alters as "pieces and fragments"Have you always done that?? We have had a struggle with acceptance of who we are and in fact, most of us still feel as if we are very separate people. Our therapist consistantly referrs to us as "parts"and every time she does, we shudder collectively....we are just not here yet I guess. If you have ever referred to yourselves differently, what made the change?? And how long did it take?
I don't refer to my alters as "pieces and fragments", in fact I don't even call them "alters", except for the sake of making myself more clear to those who are listening

Normally I will call them my "kids" because that is what fits for me, and I used to be stubborn about calling them that and nothing else, that was my comfort level. However now I am comfortable talking about my situation from a third person and calling them "alters" so that it is easier for others to understand who I am referring to.
When I talk about "pieces and fragments", I am referring to the complexity of my system.
My trauma went on for so long that my alters have parts and fragments, as do I..
Referring to a part as a piece of yourself such as the self you show in certain situations, fragments being memory
clusters that hold specific memories that can be healed and merged...
I'm sorry if it's confusing... For example I have around 4-5 alters, that have their own parts to selves, and fragments.
So... F is a dissociated part of MY system. F isn't "flat", he has a wide variety of selves (not dissociated selves) to himself,
and fragments to himself. C was a dissociated fragment of F, and once C worked through his stuff, his memories became
a part of F.
I myself have some selves (not dissociated) in my system, but I could look at F as being a branched out part of my system
that has been dissociated from me (he IS a different version of me, but we operate separately for now).
Our systems can be really unique and complicated.
I try to look at it this way when my therapist calls them "parts"- he is working with what he knows and experiences.
My experience is that F (and the others) seem to be parts of me, or 'alternate' versions of me.
It really bothered me at first, but now I just play along for therapy's sake. If you'd prefer she call them what you're comfortable with first, discuss it with her. We really enjoyed being acknowledged in this way, and since grew to trust him and now
we are not as picky with the wording, even if it seems wrong.
It might help to say that instead of a person, we are a system, because that seems to make more sense.
If you look at a community, every person makes up part of that community. They are a part of that system.
Ugh, I'm sorry, I am rambling at this point...
