I don't have DID but rather Other Specified Dissociative Disorder or OSDD. I have "alters" but don't generally have amnesia anymore when switching. I used to though.
The reason I am replying is I used to have blind rage explosions. This statement...Really struck home. Didn't have any idea what I was saying until it was over. I would throw stuff. It was nuts. I was at work once throwing chairs then "woke up" hiding under a cubicle.
My therapist really taught me how to feel all of this coming on. It was triggered by anxiety. So, if I could feel that before ir happened, I could get away from what was causing it. I never learned how to not be blind during it though. I never learned how to control it. It's horrible. But, it may help to learn what triggers it and learn how to feel it coming on.
Not sure if that helps but thought I would throw it out there.
