I experience derealization much more than I do depersonalization.. but if I'm stressed out or whatever, or in a worse state, I'll experience both.
Last night I suffered some strong hallucinations while feeling very, very distanced from "the real world." I can't remember almost anything from an 8 hour period or so today. It felt like I was really dreaming... "delirium" is a great word for it. I drank some and self-harmed some, I think. I'm feeling a lot less numb. Some of my cuts are starting to sting, and I consider that to be a good sign, if things are going to be as they are. But it troubles me that I did bad things while I lost my grasp on reality.
I made an appointment to see a doctor on Monday to talk about DP/DR and my hallucinations. For most of the day, I felt maybe 40% detached from the world, in that "mental fog" some people describe when they discuss how their DR affects them. For some reason, it climbed up a lot, and it reached that state I'd describe as 100% dissociation from the world. This has only happened to me maybe 4 or 5 times (very hard to think about it, for some reason) but it's never made me self-harm, from what I can recall. I'm nervous to go into the doctor's. As long as I don't tell him about the suicidal thoughts or self-harm, he shouldn't do anything "bad" to me, I figure... maybe I can even get on SSI...
