Benzos aren't good for anxiety in the long run, OK for occasional use, but if you build a tolerance they can make you more anxious and can be a pain to come off. How come you weren't prescribed amitriptyline? That's usually the first AD offered.

@RAllen82 Know what you mean about being stuck in fight and flight mode, that's exactly how I felt for the first 3 months or so, too much cortisol swimming about in the bloodstream. I read it can eventually lead to adrenal fatigue (which is what I may have). I found just walking helped my anxiety, takes your mind off thinking about PCS which I became obsessed with. I think it's a good idea to get some talking therapy PCS is mentally tough to cope with alone.

Don't talk to me about sleep! When I can sleep 6 hours without waking I'll be so happy.
