Yeah, it gets better. I found it seemed easier when I could let it happen, nasty as that is. And it lessened in frequency as the years went by, but it would still happen about 5 years in. After that, it only happened very occasionally, and only if I was blindsided by something, usually in the environment: like a new room, or hearing someone walking past the door outside. And it could feel intense, but it wasn't as deep, somehow.

You know I experienced the same spatial "shifting" of the room; and I didn't usually cry, but would sometimes shake and have no awareness of it.
