To me trauma would only really be processed if one does not get triggered by the memories that caused the trauma in the first place.
Bingo.
I've processed my sexual abuse. Memories don't trigger me. I've processed my physical abuse. Memories don't trigger me. I'm working on the emotional abuse. The memories are becoming less triggering.
But if someone has PTSD, those triggers are there for the rest of their life.
I disagree. The triggers can indeed be diffused to the point where they no longer bother you. Many of my triggers have been diffused. Some aren't worth the time to diffuse. Others may never be fully diffused because of their nature. Only time will tell.
but even processing such trauma will not get rid of PTSD.
I don't believe processing trauma is the KEY per se to getting rid of PTSD. Yes, it is a critical part of the process, but if we don't learn how to do self-care or learn how to use coping skills or learn how to ground ourselves, then I don't think we are fully healed, either.
I think it would be a false hope to think that this condition is simply solved by processing trauma.
I agree. This condition is very much a physical condition. I can temper my reactions to external stimuli, but once my body is flooded with adrenaline or anxiety is shooting through my veins, its no longer mental. At that point I need to calm my body down, not just my mind.
I can say that by now I have mostly gotten used to the trauma that was caused in my childhood, but is that the same thing than processing it?
No, that isn't processing, not in the least. What you describe is more of a "time heals all wounds" sort of thing. Well, not exactly, but along that mindset in that you're used to it so some of the sting is gone. Processing enables your mind to let go of the past and allows you to move forward so that your mind isn't constantly being hijacked by past memories. Unfortunately processing doesn't fix it all, but it is a very big part of the process.
