I don't know how to call it. I have BPD, but I dissociate a lot, even for a person with my disorder. Just going through the motions, missing time. Every time I walk the street, ride the bus. I remember nothing, all I can draw are blanks. It's scary, though I got used to it. Without dissociation, I'll probably be even more ill.
It's just like my life is being lived, but not by me. Also, when my emotions aren't tense, they're just plain blunt. I'm also more paranoid and psychotic that your "regular" BPD. But the dissociation. Every day, each day. For hours. And sometimes everything looks distorted. The lights are too bright, I focus on the shadows. Sometimes I don't get that that's my face, in the mirror. My arms are detached. So am I.
And I'm afraid there's nothing I can do.
