Hi Hashi,
To me the inner child concept is different to what you describe your 20 year old self to be. To me the inner child is the concept of who one is as a child and is not a traumatised state.
but I see DID and alters as something different from what I'm talking about here.
I don't know what you think of emotional parts (EP's) in structural dissociation theory. In many ways what you describe seems much more along those lines to me. It is a traumatised aspect of you at 20. ? It isn't DID as DID is further along the scale (and obviously a different ballgame) and according to structural dissociation theory PTSD falls under this concept (where there are pockets of trauma). Certain things (such as complex PTSd) mean those states can be more sophisticated.
I suspect some therapists use the terms inner child to describe a traumatised state that developed in childhood. So to be clear I would differentiate between the concept of an inner child, and a traumatised state or EP - no matter the age of that state.
child isn't one that I can relate to at all.
I've wondered if it's to do with the nature of my childhood,
How do you feel about you as a child generally? How do you feel about you in terms of being childlike and vulnerable? I think some of us feel uncomfortable not being adult and reject our child side (not assuming this for you and it is rather a question).
Personally I find the concept of an inner child very disturbing for me. I brings a sense of panic and rage (aimed at myself).
I do suspect it is usually used to connect with compassion and to build good self parenting but it hasn't worked for me and I would not be able to have a therapist suggest it. I am also hanging onto a supposed single identity for dear life.
What could the benefits be? Helping the person fill needs they never had filled in childhood. Help develop self nurturing and care. Acceptance of vulnerability when young.
Instead, I'm encouraged to see myself at 20 as part of my past and the effects of that trauma as part of my present
I think that is perfectly healthy approach no matter what the age is that the trauma occurred.
I think the separating can be a problem when people use it as a way to avoid responsibility. I guess there is the issue of self compassion and ways to make that happen but different things work for different people.
