Hi,

How come there is depersonalization disorder, but not derealization disorder? Depersonalization is someone feeling detached from their body and thoughts, and derealization is feeling like someone's surroundings aren't real.

I have experienced derealization more than depersonalization, but I've had both. I guess I'm just curious as to why one is a full-blown disorder, and another is a symptom of other disorders, like anxiety. Thanks!
