Geography was one of my worst subjects, too. Mind you, I had a crap education, full stop! :lol:
I did understand what you meant, about not believing you've ever exsisted. Even though you know you have, it sometimes feels like you haven't. Yes, that's what some other DPers have felt, too.
I only mentioned what I and other DPers have felt, to try to help you figure out if you do have DP and/or DR. Prior to when I was diagnoised with it, I didn't have access to the Internet, so I had never even heard of DP/DR before. But soon after, when I read about it and realised that everything fitted, I felt like a black cloud had lifted from me.
Even though I still suffered like hell, I think it really helped to at least know what was wrong with me. I had always known there was something else wrong with me other than Depression and Anxiety.
Anyway, WhereamI, I don't know if you know this, but if you click on the 'search', at the top right of the page, you can type in a word, or phrase and you will immediately be taken to any information on that topic (I actually only discovered this last week... Duh! :roll: ). Hope this'll help?
Take care,
