One month later and I thought I'd reply back with an update

Still alive, still 'sane' !

I started CBT - have had about 5 sessions and feel progress. I feel my levels of anxiety have dropped but are still high.

I read up on some of the symptoms, ie derealization, depersonalization etc - I've had them all.

At one point, I feared the idea of Solipism and that completely freaked me out but I've progressed past that sort of - I do still have some exisential thoughts but not as bad.

Some points:

My libido is back (!)
I am slightly happier
I am sleeping ok

On the mend hopefully!
