I can't really believe in complete remission

I KNOW, theoretically, that remission is possible and very common. I've read lots of literature that say that. But I admit I, in my intimate emotional world, have difficulty grasping it. I have difficulty grasping how a personality disorder can have remission, considering it is made of relatively stable and inflexible traits and consists of the person's entire personality rather than being, for example, an episodic mood disorder. With personality disorders, it kind of composes you intrinsically instead of being something that is on you, in my view. I compare it a bit with autism. I KNOW they are different things because autism is a neurodevelopmental disorder which was always there and will always be there, but like... both deeply and pervasively affect your way of being, thinking, feeling, behaving. There's no remission for autism, so how is there for personality disorders?

I'm not trying to be anti-recovery by the way I just genuinely kind of don't get it. Maybe the problem is that I lost hope for myself, because I can't imagine myself being significantly without the symptoms.
