"Trauma holds on." Personally, I've gone through endless cycles of thinking that I could or indeed was on the way to 100% recovery from complex traumas. Now I seem to have enough perspective to doubt that full recovery scenario. What's more important might be to give the inner critic permission to stop the analysis and just proceed with life the best I can; knowing that trauma remnant is probably stuck in place, for no reason worth agonizing over (wonder/disgust/anger is okay to a point).
The other part of this that comes to mind is how impossible this usually is to fully share with anyone, so all the pain stays hidden inside. Instead of understanding, the typical outsider's response can range from false to well-intended pity; and beyond to outright skepticism that anything like we share really happened or could have been that bad. And the proof stays invisible, and we carry it forward. And, in my experience, it never fully escapes, akin to 'the body keeps the score' if nothing else does. It isn't even logical, but we feel it.
This persistent and disguised form of 'trauma retention' has been surprising to me; I always held the belief that I would overcome, if only I worked hard enough. Well -- for sure facets might be alleviated, but I have my doubts now, after several years of growing up with this stuff, trying to ignore it, patterns being repeated, more denials, etc. Finally the realization -- that okay, how do I live now, even if trauma is indeed stuck.
