I think I know what your are talking about...straight up dissociating. When I was way younger after like 18 years of abuse.. I would be like a robot going through the motions of day to day life disconnected...barely function without caring about time or space, or what you wear or eat, but a force is running your life...without just enough spark to not die. Going through the motions of everyday living with no spirit invested...like a drone going through the motions...doing whatever...acting like whatever in a living daze...not caring hoping to die but not lucky enough to...
You end up here ...you end up there...drifting...no self concern...looking back that others ran your life as you didn't care...couldn't...

I was way beyond PTSD...I chalk that up to complex PTSD. It's on the dissociative spectrum...so it's like not infeasible. Call your T!
