I knew something was wrong for years. For some time I couldnt put a finger on what it was, then I had an epifany in the shower (lol), I realized there was a courtain between me and the world (I was a teenager feeling like that for ever). But it was very confusing to me, so it was not like this other people felt? I couldnt explain and understand much. So time went on.
I don't remember the exact time I learned about depersonalization. I search the web a lot back them and at the time I made a new self diagnose everyday. To speak the truth my confusion and bad memory probably made me forgot and remember a lot about that diagnosis (depersonalization) I identified myself with... It was a break thought reading about it, but there came other break thoughts and I was just confused on what diagnosis to believe was mine.
