Hi, I too have this horrible illness derealization.
I´ll try to keep this short, but it first came on when I was travelling 4 years ago, I believe it was brought on by a marajana (or how ever you spell it!) drink I had in India that I had a very bad reaction to. After that night I had this fear that, that horrible feeling would come back when I hadn´t had anything. Then 3 months later it did, suddenly. Complete with the anxiety attacks and depression.

I was also spacey and kept having the feeling that this wasn´t reality, as well as having sort of headachey feeling at the front of my head. Plus most scarily I had the thoughts of just ending it all...

Since then I have continued pretty much with a normal life, other than the usualy speradic set backs. I had still been on the tablets, but gradually weaned my way off them as I felt so much better. I still got the occassional feelings still, but trying to concentrate on whatever I was doing and they only ever last a day or so and then go away.
As well as the tablets I found the best way to cope was to try my best when possible to replace any negative thoughts with positive ones (I know half the time this isn´t possible, but its w
