I'm going to go on a bit of a Robin front here
Remember that the one-size-fits-all thing works 2 ways.
Although it can seem as if you are not being looked at properly, your anxiety is caused by you focusing on yourself. You may tend to single yourself out from other people and feel that as you have had it a long time and your fears are complex, you should take more looking at. CBT teached you not to care about going deeper into your thoughts and symptoms and instead, just accepting them and labelling them.
May I suggest mindfulness...have you read the mindfulness part of Robin's books? What you were saying about a symptom like fluffy head could be caused by anxiety or not but can still cause anxiety in turn - mindfulness would help you look at a sensation like that neutrally and objectively. It may or may not be caused by anxiety but you can make a mindful decision about whether it's worth "doing" something about it or letting it be and living alongside it. It does not go into the causes behind the symptom, and the accepting thereof allows you the possibility of not getting anxious from it.
With loosing your fear of panic, part of testing it out is going out there and putting your practise into daily life. With the skills you have you have no need to fear real panic as you know it will never happen. Anyone would fear a "major" panic attack, but if you lose any obsessive or phobic fear of that, then you can leave that fear somewhere in the depths of the unconscious and not think of it again.
So in summary, CBT is a different type of therapy where the focus is taken off you so you are not singled out against other sufferers. Part of the problem is often that feeling of being beyond help and alone. Try not to cultivate that thought. Everyone is able to recover.
I think mindfulness should be a vital part of therapy though, as I had a blip this week and I have had a completely different perspective on things with mindfulness and have recovered from it much quicker than usual by just watching it, being with it, and giving it as much time as it needs. If you can learn to detatch from your thoughts and sensations, you have made a huge leap forward
