I google translated one of his posts from 2006 (when he was 16)
"Now, I am, by the way, an extremely naughty person, I can be worried about virtually everything that can kill me, usually having obsessions linked to these nonsense. In all other respects, I feel good when I have friends to join and feel generally good. Last night I had sat at the tv all the time and suddenly began to focus on one and the same place for a while and then it started spinning a bit. This is probably largely pure imagination as well. After that, everything felt a bit unreal, just like in a dream. After that, I feel the same thing again that everything seems empty and unreal. Is really busy and of course, you start right now.
The feeling is extremely difficult to describe, but it feels kind of blank and feels afraid to get mentally ill or to keep this feeling forever, the sense of dependence. I am well aware that everything is real, it just does not feel so. Then when I stop thinking about it, I do not care about it, do not notice it: P but only when I start crying again, everything is amplifying ... Just wonder if this is classical hypokondri of any kind or if it can be anything?
Thankful for reply =)"
