In all fairness everybody is different. And also it depends what is considered treatable or fixed by anyone?
In my small amount of contribution to PTSD arising from childhood is that it does create some character traits for better or worse. For example, I would say before I was treated and went to therapy (basically my adult life), I would say my character was sort of shaky and underdeveloped but the upside, I made some decent decisions that took me to the right direction like jobs, relationships, and general things like making friends and having some hobbies in life...but the downside was I really did not know who I was other other than what my abusive mother drilled on me.
I was sort of polarized either well integrated and making life choices or completely disintegrated and isolated but was OK with that. I did not see that as bad but framed it as having a recharge time. Now I know that was isolation according to everybody here and in therapy process but at the time, I used my isolation time to see who I was...cause well no one else was annoying me so why was I still so sad and broken? but occasionally I will be also in bliss all alone so I sort of figured very early feelings come and go and were not under my control at all...but did not know how to take advantage of them.
Now I am in therapy intensely both dyad and group and what I know (which is still infantile steps literally and figuratively speaking), is that I can feel Feelings much better than I was before or I can distinguish or see them coming on. Before I was driven by life direction and now I am driven by minuscule steps of feelings and body sensations. Now I know how I feel now determines what happens later not the other way around of what I will do in the future will determine my feelings then. I feel more in touch.
In essence, I break down my life what is inside of me and what is outside of me. Inside of me has a lot of broken parts that I am taking care as I type here. My feelings and self parts are all over but I am aware and trying to learn how to be compassionate (more so than ever before) and how to be grateful not to beat myself for looking unconscious yesterday and thinking I am conscious today (you see what I did there ...it is never ending life examining of learning who I am in my own time and be kind to me and others along the way).
and looking outside of my life like am I independent, if not why not? and do I need others to take care of me and how exactly? do I contribute to humanity in any way whether work or spiritual or otherwise...and so far that is working OK too cause it is more concrete. external and materially I feel good so this takes some pressure off to focus on other things like the ability to change career and not be financially ruined.
Not sure if this gives you hope, answers your question or aids you in anyway, but at the end, for me it boils down how do I tell my story?
I can tell it from the perspective of the abuser - I am nothing/but a crying baby or difficult or this or that and trying to be reactive to that ( a full time job) or MY perspective that I am a small human in the big bucket of humans and will fall and hurt and get up and smile as much as I can with other humans so I am not so alone ....obviously I am choosing the latter but won't lie to you and say the first does not try to rear its ugly head now and then.
