Well, by depersonalisation I mean a sense of detachment from reality. It gradually went away as my anxiety lessened. But socially PCS made me withdraw - an injured animal response, it also knocked my confidence which I had to regain by making myself do the things I used to. Basically reclaiming normality back. I couldn't do it until I was in a more positive frame of mind. The psychological impact hangs around even when the physical symptoms fade.
