Eamon44, I'm in the same boat as you....IT SUCKS! I went through traditional PCS symptoms and then recovered, only to have them return followed-up by a single massive panic attack which has put me in the same depersonalized/derealization state like you. The philosophical and life questions/thoughts are debilitating at times. As impossible as it is, I make it a point to force myself to stop focusing, researching and educating myself on the subject when I'm feeling well. I feel like this only furthers the crippling cycle. However, for nights like tonight, where I simply feel like crap, I allow myself to "indulge".

Are your psychiatrist and psychologist visits strictly because of your current situation? And what do you discuss with them?
