Can having a victim mentality stemming from childhood abuse (in which you were a genuine victim) cause a person to have a lack of closure when feeling mistreated, but the mistreatment wasn’t overt?

Where your brain can’t process it and is trying to work out a way to fly junk of yourself as the victim when it’s not an obvious mistreatment.

So if you react badly to what you perceive is bad treatment and it feels like you have no closure, is that because your brain is trying to process it and make yourself the victim in that case? Is that where the dissociation comes in because your brain can’t process things as it’s not obvious that you’re a victim (maybe you’re even the bad one in that scenario) so it’s trying hard to find anything to make yourself the victim in your mind?
