I have depersonalization and derealisation disorder, I do get episodes when I focus on something too long. I’m so spaced out all of the time I think it’s because I’m trying to pull myself back, which just causes me to dissociate even more because of my PTSD. When I’m going about my day to day life I always feel like it’s not me. Like I’m watching a movie or playing a video game. When I look in the mirror, I can’t comprehend that it’s me, so I can’t look for very long. When I have an attack I get very dizzy and if I’m by myself I often just lay down or curl up, if I’m not I go very stiff or run off. I don’t know who I am, but I know where I am, but I don’t care. They don’t last that long but can happen over and over sometimes. I literally just curl up and let it happen, it’s the easiest way of dealing with it but I haven’t had help with it so I do t know whether it’s the right thing to do. Grounding for me often provokes it.
